Greg Magolan 9bb349e1c8 refactor: handle breaking changes in rules_nodejs 1.0.0 (#34589)
The major one that affects the angular repo is the removal of the bootstrap attribute in nodejs_binary, nodejs_test and jasmine_node_test in favor of using templated_args --node_options=--require=/path/to/script. The side-effect of this is that the bootstrap script does not get the require.resolve patches with explicitly loading the targets _loader.js file.

ayazhafiz 19944c2424 feat(compiler): record end of expression Token (#33549)
In the past, only the starting index of an expression Token has been
recorded, so a parser could demarkate the span of a token only by the
start locations of two tokens. This may lead to trailing whitespace
being included in the token span:

```html
{{ token1   + token2 }}
   ^^^^^^^^^             recorded span of `token1`
```

It's also not enough for a parser to determine the end of a token by
adding the length of the token value to the token's start location,
because lexed expression values may not exactly reflect the source code.
For example, `"d\\"e"` is lexed as a string token whose value is `d"e`.

Instead, this commit adds a `end` field to expression tokens. `end`
is one past the last index of the token source code. This will enable a
parser to determine the span of a token just by looking at that token.

This is a breaking change because the contructor interface of `Token`
has changed.

Part of #33477.

The `:` char is used as a metadata marker in `$localize` messages.

Previously, although the `:` char was being escaped, the TS AST

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.

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`.

Pete Bacon Darwin 9188751adc fix(ivy): i18n - do not render message ids unnecessarily (#32867)
In an attempt to be compatible with previous translation files
the Angular compiler was generating instructions that always
included the message id. This was because it was not possible
to accurately re-generate the id from the calls to `$localize()` alone.

In line with https://hackmd.io/EQF4_-atSXK4XWg8eAha2g this
commit changes the compiler so that it only renders ids if they are
"custom" ones provided by the template author.

NOTE:

When translating messages generated by the Angular compiler
from i18n tags in templates, the `$localize.translate()` function
will compute message ids, if no custom id is provided, using a
common digest function that only relies upon the information
available in the `$localize()` calls.

This computed message id will not be the same as the message
ids stored in legacy translation files. Such files will need to be
migrated to use the new common digest function.

This only affects developers who have been trialling `$localize`, have
been calling `loadTranslations()`, and are not exclusively using custom
ids in their templates.

Pete Bacon Darwin b741a1c3e7 fix(ivy): i18n - update the compiler to output `MessageId`s (#32594)
Now that the `$localize` translations are `MessageId` based the
compiler must render `MessageId`s in its generated `$localize` code.
This is because the `MessageId` used by the compiler is computed
from information that does not get passed through to the `$localize`
tagged string.

For example, the generated code for the following template

```html
<div id="static" i18n-title="m|d" title="introduction"></div>
```

will contain these localization statements

```ts
if (ngI18nClosureMode) {
  /**
    * @desc d
    * @meaning m
    */
  const MSG_EXTERNAL_8809028065680254561$$APP_SPEC_TS_1 = goog.getMsg("introduction");
  I18N_1 = MSG_EXTERNAL_8809028065680254561$$APP_SPEC_TS_1;
}
else {
  I18N_1 = $localize \`:m|d@@8809028065680254561:introduction\`;
}
```

Since `$localize` is not able to accurately regenerate the source-message
(and so the `MessageId`) from the generated code, it must rely upon the
`MessageId` being provided explicitly in the generated code.

The compiler now prepends all localized messages with a "metadata block"
containing the id (and the meaning and description if defined).

Note that this metadata block will also allow translation file extraction
from the compiled code - rather than relying on the legacy ViewEngine
extraction code. (This will be implemented post-v9).

Although these metadata blocks add to the initial code size, compile-time
inlining will completely remove these strings and so will not impact on
production bundle size.

This commit changes the Angular compiler (ivy-only) to generate `$localize`
tagged strings for component templates that use `i18n` attributes.

BREAKING CHANGE

Since `$localize` is a global function, it must be included in any applications
that use i18n. This is achieved by importing the `@angular/localize` package
into an appropriate bundle, where it will be executed before the renderer
needs to call `$localize`. For CLI based projects, this is best done in
the `polyfills.ts` file.

```ts
import '@angular/localize';
```

For non-CLI applications this could be added as a script to the index.html
file or another suitable script file.
