Pete Bacon Darwin 5038e5741b fix(ngcc): handle aliases in UMD export declarations (#38959)
Sometimes UMD exports appear in the following form:

```
exports.MyClass = alias1 = alias2 = <<declaration>>
```

Previously the declaration of the export would have been captured
as `alias1 = alias2 = <<declaration>>`, which the `PartialInterpreter`
would have failed on, since it cannot handle assignments.

Now we skip over these aliases capturing only the `<<declaration>>`
expression.

Fixes #38947

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
