Add a new compiler option moduleSuffixes to expand the node module resolver's search algorithm (#48189)

Browse Source 
* Add moduleSuffixes compiler option and related tests. Update baselines for compiler options tests.

* Add a flag to the command-line parser which allows "list" params to preserve "falsy" values such as empty strings. Falsy values are normally stripped out.

* Add tests. Rework resolver logic to only run module-suffix code when needed.

* PR feedback

* Add test

* Remove unnecessary conditional.
