Pete Bacon Darwin 97e13991c5 fix(ngcc): identifier ModuleWithProviders functions in IIFE wrapped classes (#37206)
In ES2015 IIFE wrapped classes, the identifier that would reference the class
of the NgModule may be an alias variable. Previously the `Esm2015ReflectionHost`
was not able to match this alias to the original class declaration. This resulted
in failing to identify some `ModuleWithProviders` functions in such case.

These IIFE wrapped classes were introduced in TypeScript 3.9, which is why
this issue is only recently appearing. Since 9.1.x does not support TS 3.9
there is no reason to backport this commit to that branch.

Fixes #37189

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
