Alex Rickabaugh 16c7441c2f refactor(compiler-cli): introduce the TemplateTypeChecker abstraction (#38105)
This commit significantly refactors the 'typecheck' package to introduce a
new abstraction, the `TemplateTypeChecker`. To achieve this:

* a 'typecheck:api' package is introduced, containing common interfaces that
  consumers of the template type-checking infrastructure can depend on
  without incurring a dependency on the template type-checking machinery as
  a whole.
* interfaces for `TemplateTypeChecker` and `TypeCheckContext` are introduced
  which contain the abstract operations supported by the implementation
  classes `TemplateTypeCheckerImpl` and `TypeCheckContextImpl` respectively.
* the `TemplateTypeChecker` interface supports diagnostics on a whole
  program basis to start with, but the implementation is purposefully
  designed to support incremental diagnostics at a per-file or per-component
  level.
* `TemplateTypeChecker` supports direct access to the type check block of a
  component.
* the testing utility is refactored to be a lot more useful, and new tests
  are added for the new abstraction.

Angular Compatibility Compiler (ngcc)

This compiler will convert node_modules compiled with ngc, into node_modules which appear to have been compiled with ngtsc.

This conversion will allow such "legacy" packages to be used by the Ivy rendering engine.

Building

The project is built using Bazel:

yarn bazel build //packages/compiler-cli/ngcc

Unit Testing

The unit tests are built and run using Bazel:

yarn bazel test //packages/compiler-cli/ngcc/test

Integration Testing

There are tests that check the behavior of the overall executable:

yarn bazel test //packages/compiler-cli/ngcc/test:integration
