Speeds up the dev-turnaround by only bundling types when packaging. Currently
bundling occurs for all the `ng_module` targets in devmode.
This has various positive benefits:
* Avoidance of this rather slower operation in development
* Makes APF-built packages also handle types for `ts_library` targets consistently.
* Allows us to ensure APF entry-points have `d.ts` _always_ bundled (working with ESM
module resolution in TypeScript -- currently experimental)
* Allows us to remove the secondary `package.json` files from APF (maybe APF v14? - seems
low-impact). This would clean-up the APF even more and fix resolution issues (like in Vite)

We recently refactored how the ng package rule deals with static files.
As part of this refactoring, transitive files outside of the current
Bazel package were flagged as errors, while previously this was just
ignored. We need to revert back this behavior (even though code remains
much simpler and predicable now) since sass library targets for example
reference all transtive files in the default info and break packages then

Currently the `ng_package` rule does not support generated
`package.json` files. Generated `package.json` files are sometimes
useful when e.g. dependencies are automatically inserted (e.g.
many dependencies in the components repo for the MDC deps)
Currently the `package.json` files would be copied as part of
the `data` attribute, but they would not be processed. i.e. missing
out on the `exports` field and more.
We can simplify the rule attributes and make this more ergonomic.

The APF v13 `ng_package` rule will generate the `exports` field if not
set. Currently it allows for additional subpath entries to be configured
manually. The packager does not allow for custom conditions in subpath
exports which are auto-generated.
This is sometimes useful and necessary though. e.g. in Angular Material,
we also need to expose the index Sass file through a `sass` conditional
that the Webpack Sass loader will pick up. For this, the packager needs
to support manual additional conditions (as long as they do not
conflict).

This commit implements partial compilation APF v13 for the
`ng_package` rule. The changes involve the following things:
1. Requesting the partial compilation output for all targets (and
its transitives) in the `deps` or `srcs` attributes.
2. Downleveling of ES2020 prodmode output to a FESM2015 file.
3. Cleanup of file resolution. Previusly, execroot file paths (which are
passed to the packager tool) were composed manually. This is prone to
mistakes and breaks with transitions.
A lot of this code can be simplified by passing the necessary Bazel
`File` information as JSON. This also simplifies the packager tool
significantly (and makes it more readable..)
4. Remoal of UMD bundles. This also allows us remove the `globals` rule
attribute with `externals` (we do not need any UMD global identifier
names anymore).
5. The `package.json` will set the `exports` field and use subpath
exports to make module resolution work for ESM consumers.
6. TSLib is also always set as `external` now. Previously it had to be
added as `dep` to the `ng_package` rule as UMD files bundled `tslib`.
7. The `include_devmode_srcs` option has been removed. This option was
an addition to APF that allowed the `@angular/compiler` to ship
non-flattened ES5 CommonJS sources. We want to keep APF consistent
and not allow such exceptions. Compiler is now a strict APF package
as well, and the compiler-cli just needs to go through the primary
entry-point for things it needs (or it bundles the necessary parts
into the CLI.)
Overall, these are all changes. A lot of changes to make the packager
rule and tool more readable and Bazel-idiomatic were made as well. This
allows us to easier make packaging changes in the future, and it's more
future-proof if we ever change how inputs (like `ng_module` targets) are
generated (e.g. consider a case where we'd use the `ts_project` rule).
PR Close#43431
Adds a new entry-point to the `@angular/bazel` `ng_package` test that
contains numbers in the name. e.g. `example/a11y`. This test is added
to replicate a bug where the UMD module export for such entry-points
is incorrectly generated. i.e. `example.a11Y` is generated instead of
`example.a11y`.
PR Close#35792
This lets projects like Material change ng_package "bundle index" files to non-conflicting paths
Currently packages like @angular/core ship with the generated metadata
in a path like 'core.js' which overwrites one of the inputs.
Angular material puts the generated file in a path like 'index.js'
Either way these files generated by ng_module rules have the potential
to collide with inputs given by the user, which results in an error.
Instead, give users the freedom to choose a different non-conflicting name.
Also this refactors the ng_package rule, removing the redundant
secondary_entry_points attribute.
Instead, we assume that any ng_module in the deps with a module_name
attribute is a secondary entry point.
