[api-extractor]: TS paths aliases force bundling cross package definitions when rolluping dts

[Hotell]

Summary

We wanna leverage stripping @internal APIs from rolluped dts definition by leveraging publicTrimmedFilePath config. Unfortunately things doesn't work as one would expect.

Actual
When TS Paths aliases are used, cross package type declarations are always inlined(bundled), although there is no bundledPackages being applied.

Expected
No matter if yarn workspaces/lerna/symlink resolution or TS path aliases is applied within monorepo to resolve absolute package paths, api-extractor should not inline(bundle) cross package type definitions.

Steps:

1. run yarn build
2. check output:

check packages/one/dist/public.d.ts:

• ✅ internalOne has been stripped as expected (inside package API)
• 🐛 Attributes re-export hasn't been stripped (3rd party/node_modules package) - This should have been removed !
  - [api-extractor]: @internal APIs from 3rd party deps/node_modules are not removed in rolluped dts #3444

check packages/two/dist/public.d.ts:

• ✅ internalOne has been stripped as expected (re-export from a different within repo package API)
• 🐛 inlined Baseball and Hello from @org/two package (re-export from a different within repo package ) - should have been only re-export of Baseball !
