Pete Bacon Darwin 2cdb3a079d feat(ivy): i18n - implement compile-time inlining (#32881)
This commit implements a tool that will inline translations and generate
a translated copy of a set of application files from a set of translation
files.

Pete Bacon Darwin d24ade91b8 fix(ivy): i18n - support colons in $localize metadata (#32867)
Metadata blocks are delimited by colons. Previously the code naively just
looked for the next colon in the string as the end marker.

This commit supports escaping colons within the metadata content.
The Angular compiler has been updated to add escaping as required.

Pete Bacon Darwin 97d5700456 fix(ivy): i18n - better translation warnings (#32867)
The missing translation and invalid placeholder warnings now contain the
"meaning" if one was provided.

Pete Bacon Darwin 601f87c2ec fix(ivy): i18n - throw an error if a translation contains an invalid placeholder (#32867)
Previously if a translation contains a placeholder that
does not exist in the message being translated, that
placeholder is evaluated as `undefined`.

Translations should never contain such placeholder names
so now `translate` will throw a helpful error in instead.

cexbrayat f1b1de9a3d fix(ivy): i18n - start generated placeholder name at `PH` (#32493)
Currently the expressions used in a template string are automatically named
`PH_1`, `PH_2`, etc. Whereas interpolations used in i18n templates generate
placeholders automatically named `INTERPOLATION`, `INTERPOLATION_1`, etc.

This commit aligns the behaviors by starting the generated placeholder
names for expressions at `PH`, then `PH_1`, etc.

It also documents this behavior in the documentation of `$localize` as
it was not mentioned before.

Pete Bacon Darwin 357aa4a097 fix(ivy): i18n - use `MessageId` for matching translations (#32594)
As discussed in https://hackmd.io/33M5Wb-JT7-0fneA0JuHPA `SourceMessage`
strings are not sufficient for matching translations.

This commit updates `@angular/localize` to use `MessageId`s for translation
matching instead.

Also the run-time translation will now log a warning to the console if a
translation is missing.

BREAKING CHANGE:

Translations (loaded via the `loadTranslations()` function) must now use
`MessageId` for the translation key rather than the previous `SourceMessage`
string.

Pete Bacon Darwin 870d189433 refactor(ivy): i18n - run-time translation API to use message-id (#32594)
Previously the translation key used for translations was the `SourceMessage`
but it turns out that this is insufficient because "meaning" and "custom-id"
metadata affect the translation key.

Now run-time translation is keyed off the `MessageId`.

Pete Bacon Darwin fd62ed66e3 test(ivy): i18n - re-enable skipped tests (#32594)
The `packages/localize/test/utils` folder was not being
included in the unit tests because the glob for the spec
files was only looking in the top level folder.

Pete Bacon Darwin 2bf5606bbe feat(ivy): i18n - reorganize entry-points for better reuse (#32488)
This is a refactoring that moves the source code around to provide a better
platform for adding the compile-time inlining.

1. Move the global side-effect import from the primary entry-point to a
   secondary entry-point @angular/localize/init.

   This has two benefits: first it allows the top level entry-point to
   contain tree-shakable shareable code; second it gives the side-effect
   import more of an "action" oriented name, which indicates that importing
   it does something tangible

2. Move all the source code into the top src folder, and import the localize
   related functions into the localize/init/index.ts entry-point.

   This allows the different parts of the package to share code without
   a proliferation of secondary entry-points (i.e. localize/utils).

3. Avoid publicly exporting any utilities at this time - the only public
   API at this point are the global `$localize` function and the two runtime
   helpers `loadTranslations()` and `clearTranslations()`.
   This does not mean that we will not expose additional helpers for 3rd
   party tooling in the future, but it avoid us preemptively exposing
   something that we might want to change in the near future.

Notes:

It is not possible to have the `$localize` code in the same Bazel package
as the rest of the code. If we did this, then the bundled `@angular/localize/init`
entry-point code contains all of the helper code, even though most of it is not used.

Equally it is not possible to have the `$localize` types (i.e. `LocalizeFn`
and `TranslateFn`) defined in the `@angular/localize/init` entry-point because
these types are needed for the runtime code, which is inside the primary
entry-point. Importing them from `@angular/localize/init` would run the
side-effect.

The solution is to have a Bazel sub-package at `//packages/localize/src/localize`
which contains these types and the `$localize` function implementation.
The primary `//packages/localize` entry-point imports the types without
any side-effect.
The secondary `//packages/localize/init` entry-point imports the `$localize`
function and attaches it to the global scope as a side-effect, without
bringing with it all the other utility functions.

BREAKING CHANGES:

The entry-points have changed:

* To attach the `$localize` function to the global scope import from
`@angular/localize/init`. Previously it was `@angular/localize`.

* To access the `loadTranslations()` and `clearTranslations()` functions,
import from `@angular/localize`. Previously it was `@angular/localize/run_time`.
