George Kalpakas cfbb1a1e77 fix(ngcc): correctly detect dependencies in CommonJS (#34528)
Previously, `CommonJsDependencyHost.collectDependencies()` would only
find dependencies via imports of the form `var foo = require('...');` or
`var foo = require('...'), bar = require('...');` However, CommonJS
files can have imports in many different forms. By failing to recognize
other forms of imports, the associated dependencies were missed, which
in turn resulted in entry-points being compiled out-of-order and failing
due to that.

While we cannot easily capture all different types of imports, this
commit enhances `CommonJsDependencyHost` to recognize the following
common forms of imports:

- Imports in property assignments. E.g.:
  `exports.foo = require('...');` or
  `module.exports = {foo: require('...')};`

- Imports for side-effects only. E.g.:
  `require('...');`

- Star re-exports (with both emitted and imported heleprs). E.g.:
  `__export(require('...'));` or
  `tslib_1.__exportStar(require('...'), exports);`
