George Kalpakas b6e8847967 fix(ngcc): handle imports in dts files when processing CommonJS (#35191)
When statically evaluating CommonJS code it is possible to find that we
are looking for the declaration of an identifier that actually came from
a typings file (rather than a CommonJS file).

Previously, the CommonJS reflection host would always try to use a
CommonJS specific algorithm for finding identifier declarations, but
when the id is actually in a typings file this resulted in the returned
declaration being the containing file of the declaration rather than the
declaration itself.

Now the CommonJS reflection host will check to see if the file
containing the identifier is a typings file and use the appropriate
stategy.

(Note: This is the equivalent of #34356 but for CommonJS.)

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
