JoostK ae142a6827 refactor(ngcc): avoid repeated file resolution during dependency scan (#32181 )

During the recursive processing of dependencies, ngcc resolves the
requested file to an actual location on disk, by testing various
extensions. For recursive calls however, the path is known to have been
resolved in the module resolver. Therefore, it is safe to move the path
resolution to the initial caller into the recursive process.

Note that this is not expected to improve the performance of ngcc, as
the call to `resolveFileWithPostfixes` is known to succeed immediately,
as the provided path is known to exist without needing to add any
postfixes. Furthermore, the FileSystem caches whether files exist, so
the additional check that we used to do was cheap.

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
