feat(ngcc): enable private NgModule re-exports in ngcc on request (#33177)

This commit adapts the private NgModule re-export system (using aliasing) to
ngcc. Not all ngcc compilations are compatible with these re-exports, as
they assume a 1:1 correspondence between .js and .d.ts files. The primary
concern here is supporting them for commonjs-only packages.
