Before this change `[class]` and `[className]` were both converted into `ɵɵclassMap`. The implication of this is that at runtime we could not differentiate between the two and as a result we treated `@Input('class')` and `@Input('className)` as equivalent.
This change makes `[class]` and `[className]` distinct. The implication of this is that `[class]` becomes `ɵɵclassMap` instruction but `[className]` becomes `ɵɵproperty' instruction. This means that `[className]` will no longer participate in styling and will overwrite the DOM `class` value.

The `ng_package` rule currently creates incorrect UMD module exports
if an entry-point has a module name with numbers included.
For example, consider an entry-point called `@angular/cdk/a11y`. The UMD
module name should be `ng.cdk.a11y`. Instead, `ng_package` currently generates
an UMD module export called `ng.cdk.a11Y`.
This is because the logic for converting dash-case to camel case is
invalid as it uses Starlark's `title()` method. The title method
converts text to title case while we actually just want to capitalize
the first letter of a dash-case segment.
Fixes angular/components#18652.

This commit extends the range of tNode types that may have local refs to include `TNodeType.Container` to account for `<ng-template>`s. Original changes in https://github.com/angular/angular/pull/33415 didn't include that type and as a result, an error is thrown at runtime in case an i18n block contains an `<ng-template>` with local refs.

When the `NgIf` directive is used in a template, its context variables
can be used to capture the bound value. This is typically used together
with a pipe or function call, where the resulting value is captured in a
context variable. There's two syntax forms available:
1. Binding to `NgIfContext.ngIf` using the `as` syntax:
```html
<span *ngIf="(user$ | async) as user">{{user.name}}</span>
```
2. Binding to `NgIfContext.$implicit` using the `let` syntax:
```html
<span *ngIf="user$ | async; let user">{{user.name}}</span>
```
Because of the semantics of `ngIf`, it is known that the captured
context variable is non-nullable, however the template type checker
would not consider them as such and still report errors when
`strictNullTypes` is enabled.
This commit updates `NgIf`'s context guard to make the types of the
context variables non-nullable, avoiding the issue.

This commit removes the `NullAstVisitor` and `visitAstChildren` exported
from `packages/compiler/src/expression_parser/ast.ts` because they
contain duplicate and buggy implementation, and their use cases could be
sufficiently covered by `RecursiveAstVisitor` if the latter implements the
`visit` method. This use case is only needed in the language service.
With this change, any visitor that extends `RecursiveAstVisitor` could
just define their own `visit` function and the parent class will behave
correctly.
A bit of historical context:
In language service, we need a way to tranverse the expression AST in a
selective manner based on where the user's cursor is. This means we need a
"filtering" function to decide which node to visit and which node to not
visit. Instead of refactoring `RecursiveAstVisitor` to support this,
`visitAstChildren` was created. `visitAstChildren` duplicates the
implementation of `RecursiveAstVisitor`, but introduced some bugs along
the way. For example, in `visitKeyedWrite`, it visits
```
obj -> key -> obj
```
instead of
```
obj -> key -> value
```
Moreover, because of the following line
```
visitor.visit && visitor.visit(ast, context) || ast.visit(visitor, context);
```
`visitAstChildren` visits every node *twice*.

The `packages/localize/src/tools` folder was excluded
from the top level `tsconfig.json` which meant that in IDEs
these source files were not being given the correct configuration.
It was originally excluded because it required the native `node` typings
but this is no longer a requirement.
Removing this folder from the exclusion list exposed a new issue
where there was a typings mismatch between `@babel/...` sources
and the associated `@types/babel__...` typings packages.
A clean up of the package.json and yarn.lock appears to fix this.

For view and content queries, the Ivy compiler attempts to statically
evaluate the predicate token so that string predicates containing
comma-separated reference names can be split into an array of strings
during compilation. When the predicate is a dynamic value that cannot be
statically interpreted at compile time, the compiler would previously
produce an error. This behavior breaks a use-case where an `InjectionToken`
is being used as query predicate, as the usage of the `new` keyword
prevents such predicates from being statically evaluated.
This commit changes the behavior to no longer produce an error for
dynamic values. Instead, the expression is emitted as is into the
generated code, postponing the evaluation to happen at runtime.

Source-maps in the wild could be badly formatted,
causing the source-map flattening processing to fail
unexpectedly. Rather than causing the whole of ngcc
to crash, we gracefully fallback to just returning the
generated source-map instead.
PR Close#35718
Previously when rendering flattened source-maps, it was assumed that no
mapping would come from a line that is outside the lines of the actual
source content. It turns out this is not a valid assumption.
Now the code that renders flattened source-maps will handle such
mappings, with the additional benefit that the rendered source-map
will only contain mapping lines up to the last mapping, rather than a
mapping line for every content line.

In #35702, the payload size limit for Ivy builds was bumped to account
for small incremental increases in recent PRs. The ViewEngine size has
also increased similarly (~500B), but it was not updated in #35702,

6B).
This commit bumps the ViewEngine size limit too.

It's possible to pass a directive as an input to itself. Consider:
```html
<some-cmp #ref [value]="ref">
```
Since the template type-checker attempts to infer a type for `<some-cmp>`
using the values of its inputs, this creates a circular reference where the
type of the `value` input is used in its own inference:
```typescript
var _t0 = SomeCmp.ngTypeCtor({value: _t0});
```
Obviously, this doesn't work. To resolve this, the template type-checker
used to generate a `null!` expression when a reference would otherwise be
circular:
```typescript
var _t0 = SomeCmp.ngTypeCtor({value: null!});
```
This effectively asks TypeScript to infer a value for this context, and
works well to resolve this simple cycle. However, if the template
instead tries to use the circular value in a larger expression:
```html
<some-cmp #ref [value]="ref.prop">
```
The checker would generate:
```typescript
var _t0 = SomeCmp.ngTypeCtor({value: (null!).prop});
```
In this case, TypeScript can't figure out any way `null!` could have a
`prop` key, and so it infers `never` as the type. `(never).prop` is thus a
type error.
This commit implements a better fallback pattern for circular references to
directive types like this. Instead of generating a `null!` in place for the
reference, a type is inferred by calling the type constructor again with
`null!` as its input. This infers the widest possible type for the directive
which is then used to break the cycle:
```typescript
var _t0 = SomeCmp.ngTypeCtor(null!);
var _t1 = SomeCmp.ngTypeCtor({value: _t0.prop});
```
This has the desired effect of validating that `.prop` is legal for the
directive type (the type of `#ref`) while also avoiding a cycle.

NG6002/NG6003 are errors produced when an NgModule being compiled has an
imported or exported type which does not have the proper metadata (that is,
it doesn't appear to be an @NgModule, or @Directive, etc. depending on
context).
Previously this error message was a bit sparse. However, Github issues show
that this is the most common error users receive when for whatever reason
ngcc wasn't able to handle one of their libraries, or they just didn't run
it. So this commit changes the error message to offer a bit more useful
context, instructing users differently depending on whether the class in
question is from their own project, from NPM, or from a monorepo-style local
dependency.
