Adds support for TypeScript 4.8 and resolves some issues that came up as a result of the update.
Most of the issues came from some changes in TypeScript where the `decorators` and `modifiers` properties were removed from most node types, and were combined into a single `modifiers` array. Since we need to continue supporting TS 4.6 and 4.7 until v15, I ended up creating a new `ngtsc/ts_compatibility` directory to make it easier to reuse the new backwards-compatible code.
PR Close#47038
Fixes that the integration test size trackings stopped working due to
the recent refactorings (switch to the rule from `@angular/dev-infra-private`).
The size-tracking does not integrate very-well into Bazel and needs
a better solution in the future, allowing for RBE and Windows support,
but currently with the new rule/setup/structure the tracking does not
validate sizes because:
* The `dist/*.js` argument to the tracking script got expanded and
messed up the indices. It should be passed as a literal. This now
surfaced because the new rule runs commands in a shell.
* The name for the size goldens were not computed properly because they
were based on `ctx.attr.name`, but given the new structure, the test
targets are always named `test`.
PR Close#44430
Sets up the test targets for integration tests with the new rule.
The targets will match the configuration of the previous integration
test setup (through the dictionary in a `bzl` file).
Note: We already add `setup_chromium` based on whether Chromium tests
run as part of this integration test. In a follow-up commit we can then
remove puppeteer and rely on the Bazel-managed version of Chromium.
