Pete Bacon Darwin 47666f548c fix(ngcc): handle CommonJS re-exports by reference (#34254)
In TS we can re-export imports using statements of the form:

```
export * from 'some-import';
```

This can be downleveled in CommonJS to either:

```
__export(require('some-import'));
```

or

```
var someImport = require('some-import');
__export(someImport);
```

Previously we only supported the first downleveled version.
This commit adds support for the second version.

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.

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
