Use node moduleResolution everywhere (#47687)

TestRunner was already using it, but upstream projects (e.g. Compiler) were not, causing TestRunner to re-parse and re-bind all upstream files in (at least) editor scenarios), slowing down initial project load.

In local testing, this cut a find-all-refs call in checker.ts from 5s to 2.5s.
