George Kalpakas c3271ac22a fix(ngcc): recognize re-exports with imported TS helpers in CommonJS and UMD (#34527)
Previously, the `CommonJsReflectionHost` and `UmdReflectionHost` would
only recognize re-exports of the form `__export(...)`. This is what
re-exports look like, when the TypeScript helpers are emitted inline
(i.e. when compiling with the default [TypeScript compiler options][1]
that include `noEmitHelpers: false` and `importHelpers: false`).

However, when compiling with `importHelpers: true` and [tslib][2] (which
is the recommended way for optimized bundles), the re-exports will look
like: `tslib_1.__exportStar(..., exports)`
These types of re-exports were previously not recognized by the
CommonJS/UMD `ReflectionHost`s and thus ignored.

This commit fixes this by ensuring both re-export formats are
recognized.
