💅 useImportExtensions for actual file extension on disk

[huseeiin]

like deno, the extension in the import should match the actual extension of the file, so .js would not work for .tsx
you can leverage node's import.meta.resolve to determine the actual extension

Indeed, I thunk this makes sense because TypeScript now supports an option that supports importing TS files directly with the .ts extension: rewriteRelativeImportExtensions.

With the dependency graph that we now have, we can actually see which file (including extension!) an import resolves to, so we should be able to update useImportExtensions accordingly. I've created a task for this: #5328
