crisbeto 66725b7b37 perf(ivy): move local references into consts array (#33129)
Follow-up from #32798. Moves the local references array into the component def's `consts` in order to make it compress better.

Before:
```
const _c0 = ['foo', ''];

SomeComp.ngComponentDef = defineComponent({
  template: function() {
    element(0, 'div', null, _c0);
  }
});
```

After:
```
SomeComp.ngComponentDef = defineComponent({
  consts: [['foo', '']],
  template: function() {
    element(0, 'div', null, 0);
  }
});
```

JoostK ce30888a26 feat(ivy): graceful evaluation of unknown or invalid expressions (#33453)
During static evaluation of expressions within ngtsc, it may occur that
certain expressions or just parts thereof cannot be statically
interpreted for some reason. The static interpreter keeps track of the
failure reason and the code path that was evaluated by means of
`DynamicValue`, which will allow descriptive errors. In some situations
however, the static interpreter would throw an exception instead,
resulting in a crash of the compilation. Not only does this cause
non-descriptive errors, more importantly does it prevent the evaluated
result from being partial, i.e. parts of the result can be dynamic if
their value does not have to be statically available to the compiler.

This commit refactors the static interpreter to never throw errors for
certain expressions that it cannot evaluate.

Before this change instantiating multiple directives on the same

This commint re-organises code around directive instance creation

centralised in one function (at the expense of patching logic
duplication for root node).

It seems that with Bazel 1.0.0 setting `--incompatible_list_based_execution_strategy_selection=false` no longer works around the issue with npm_package that it did when it was added.

This commit removes both `—incompatible_list_based_execution_strategy_selection=false` as well as `build:remote --spawn_strategy=remote` which means that Bazel will do the default behavior of picking the first available strategy from the default list, which is `remote,worker,sandboxed,local`.

JoostK 8d15bfa6ee fix(ivy): allow abstract directives to have an invalid constructor (#32987)
For abstract directives, i.e. directives without a selector, it may
happen that their constructor is called explicitly from a subclass,
hence its parameters are not required to be valid for Angular's DI
purposes. Prior to this commit however, having an abstract directive
with a constructor that has parameters that are not eligible for
Angular's DI would produce a compilation error.

A similar scenario may occur for `@Injectable`s, where an explicit
`use*` definition allows for the constructor to be irrelevant. For
example, the situation where `useFactory` is specified allows for the
constructor to be called explicitly with any value, so its constructor
parameters are not required to be valid. For `@Injectable`s this is
handled by generating a DI factory function that throws.

This commit implements the same solution for abstract directives, such
that a compilation error is avoided while still producing an error at
runtime if the type is instantiated implicitly by Angular's DI
mechanism.

Alex Rickabaugh b381497126 feat(ngcc): add a migration for undecorated child classes (#33362)
In Angular View Engine, there are two kinds of decorator inheritance:

1) both the parent and child classes have decorators

This case is supported by InheritDefinitionFeature, which merges some fields
of the definitions (such as the inputs or queries).

2) only the parent class has a decorator

If the child class is missing a decorator, the compiler effectively behaves
as if the parent class' decorator is applied to the child class as well.
This is the "undecorated child" scenario, and this commit adds a migration
to ngcc to support this pattern in Ivy.

This migration has 2 phases. First, the NgModules of the application are
scanned for classes in 'declarations' which are missing decorators, but
whose base classes do have decorators. These classes are the undecorated
children. This scan is performed recursively, so even if a declared class
has a base class that itself inherits a decorator, this case is handled.

Next, a synthetic decorator (either @Component or @Directive) is created
on the child class. This decorator copies some critical information such
as 'selector' and 'exportAs', as well as supports any decorated fields
(@Input, etc). A flag is passed to the decorator compiler which causes a
special feature `CopyDefinitionFeature` to be included on the compiled
definition. This feature copies at runtime the remaining aspects of the
parent definition which `InheritDefinitionFeature` does not handle,
completing the "full" inheritance of the child class' decorator from its
parent class.

Alex Rickabaugh 818c514968 feat(ivy): add a runtime feature to copy cmp/dir definitions (#33362)
This commit adds CopyDefinitionFeature, which supports the case where an
entire decorator (@Component or @Directive) is inherited from parent to
child.

The existing inheritance feature, InheritDefinitionFeature, supports merging
of parent and child definitions when both were originally present. This
merges things like inputs, outputs, host bindings, etc.

CopyDefinitionFeature, on the other hand, compensates for a definition that
was missing entirely on the child class, by copying fields that aren't
ordinarily inherited (like the template function itself).

This feature is intended to only be used as part of ngcc code generation.

JoostK 6b267482d7 feat(ngcc): enable migrations to apply schematics to libraries (#33362)
When upgrading an Angular application to a new version using the Angular
CLI, built-in schematics are being run to update user code from
deprecated patterns to the new way of working. For libraries that have
been built for older versions of Angular however, such schematics have
not been executed which means that deprecated code patterns may still be
present, potentially resulting in incorrect behavior.

Some of the logic of schematics has been ported over to ngcc migrations,
which are automatically run on libraries. These migrations achieve the
same goal of the regular schematics, but operating on published library
sources instead of used code.

JoostK 3858b26211 refactor(ivy): mark synthetic decorators explicitly (#33362)
In ngcc's migration system, synthetic decorators can be injected into a
compilation to ensure that certain classes are compiled with Angular
logic, where the original library code did not include the necessary
decorators. Prior to this change, synthesized decorators would have a
fake AST structure as associated node and a made-up identifier. In
theory, this may introduce issues downstream:

1) a decorator's node is used for diagnostics, so it must have position
information. Having fake AST nodes without a position is therefore a
problem. Note that this is currently not a problem in practice, as
injected synthesized decorators would not produce any diagnostics.

2) the decorator's identifier should refer to an imported symbol.
Therefore, it is required that the symbol is actually imported.
Moreover, bundle formats such as UMD and CommonJS use namespaces for
imports, so a bare `ts.Identifier` would not be suitable to use as
identifier. This was also not a problem in practice, as the identifier
is only used in the `setClassMetadata` generated code, which is omitted
for synthetically injected decorators.

To remedy these potential issues, this commit makes a decorator's
identifier optional and switches its node over from a fake AST structure
to the class' name.

This commit ports the "missing-injectable" schematic to a migration that

JoostK 0d9be22023 feat(ivy): strictness flags for template type checking (#33365)
The template type checking abilities of the Ivy compiler are far more
advanced than the level of template type checking that was previously
done for Angular templates. Up until now, a single compiler option
called "fullTemplateTypeCheck" was available to configure the level
of template type checking. However, now that more advanced type checking
is being done, new errors may surface that were previously not reported,
in which case it may not be feasible to fix all new errors at once.

Having only a single option to disable a large number of template type
checking capabilities does not allow for incrementally addressing newly
reported types of errors. As a solution, this commit introduces some new
compiler options to be able to enable/disable certain kinds of template
type checks on a fine-grained basis.

For elements that have a text attribute, it may happen that the element
is matched by a directive that consumes the attribute as an input. In
that case, the template type checker will validate the correctness of
the attribute with respect to the directive's declared type of the

Since empty attributes are assigned the empty string at runtime, the
template type checker would report an error for this template.

JoostK a42057d0f8 fix(ivy): support abstract directives in template type checking (#33131)
Recently it was made possible to have a directive without selector,
which are referred to as abstract directives. Such directives should not
be registered in an NgModule, but can still contain decorators for
inputs, outputs, queries, etc. The information from these decorators and
the `@Directive()` decorator itself needs to be registered with the
central `MetadataRegistry` so that other areas of the compiler can
request information about a given directive, an example of which is the
template type checker that needs to know about the inputs and outputs of
directives.

Prior to this change, however, abstract directives would only register
themselves with the `MetadataRegistry` as being an abstract directive,
without all of its other metadata like inputs and outputs. This meant
that the template type checker was unable to resolve the inputs and
outputs of these abstract directives, therefore failing to check them
correctly. The typical error would be that some property does not exist
on a DOM element, whereas said property should have been bound to the
abstract directive's input.

This commit fixes the problem by always registering the metadata of a
directive or component with the `MetadataRegistry`. Tests have been
added to ensure abstract directives are handled correctly in the
template type checker, together with tests to verify the form of
abstract directives in declaration files.

ayazhafiz 3d11355fec test(compiler): add expression absolute span tests for `TemplateAst`s (#33253)
Previously, we had tested that expressions parsed in a Render3 AST
had correctly-defined absolute spans (spans relative to the entire
template, not the local expression). Sometimes we use Template ASTs
rather than Render3 ASTs, and it's desirable to test for correct
expression spans in the template parser as well.

Adding these tests resolved one bug, similar to the one fixed in
fd4fed14d8, where expressions in the value
of a template attribute were not given an absolute span corresponding to
the start of the attribute name rather than the start of the attribute
value.

The diff on this commit is large, partially because it involves some
structural changes of the template parser testing layout. In particular,
the following is done:

1. Move `createMeta*`-like functions from `template_parser_spec.ts` to
   be exported from a new test utility file.
2. Create an `ExpressionSourceHumanizer`, similar to the one created in
   b04488d692, to allow convenient testing
   of expressions' locations.
3. Create `template_parser_absolute_span_spec.ts`, testing the spans of
   expressions parsed by the template parser. This is very similar to
   the `r3_ast_absolute_span_spec`.

Alex Rickabaugh f1269d98dc feat(ivy): input type coercion for template type-checking (#33243)
Often the types of an `@Input`'s field don't fully reflect the types of
assignable values. This can happen when an input has a getter/setter pair
where the getter always returns a narrow type, and the setter coerces a
wider value down to the narrow type.

For example, you could imagine an input of the form:

```typescript
@Input() get value(): string {
  return this._value;
}

set value(v: {toString(): string}) {
  this._value = v.toString();
}
```

Here, the getter always returns a `string`, but the setter accepts any value
that can be `toString()`'d, and coerces it to a string.

Unfortunately TypeScript does not actually support this syntax, and so
Angular users are forced to type their setters as narrowly as the getters,
even though at runtime the coercion works just fine.

To support these kinds of patterns (e.g. as used by Material), this commit
adds a compiler feature called "input coercion". When a binding is made to
the 'value' input of a directive like MatInput, the compiler will look for a
static field with the name ngAcceptInputType_value. If such a field is found
the type-checking expression for the input will use the static field's type
instead of the type for the @Input field,allowing for the expression of a
type conversion between the binding expression and the value being written
to the input's field.

To solve the case above, for example, MatInput might write:

```typescript
class MatInput {
  // rest of the directive...

  static ngAcceptInputType_value: {toString(): string};
}
```
