Prepare module resolution for resolving TS extensions

[andrewbranch]

This is all the stuff from #50153 that will get reused for --moduleResolution hybrid. We don’t necessarily need to merge this first (though I tried to make it independently mergeable for the most part); I can just base --moduleResolution hybrid off of this branch, as it would be easier to review the two diffs separately.

[andrewbranch]

Nothing should change here because this is mostly adding code that no existing projects are able to touch, but:

@typescript-bot perf test this
@typescript-bot run top100

[typescript-bot]

Heya @andrewbranch, I've started to run the perf test suite on this PR at c6b963b. You can monitor the build here.

Update: The results are in!

[typescript-bot]

@andrewbranch
The results of the perf run you requested are in!

Here they are:
