Support template literals in preProcess (fixes #33680)

[IllusionMH]

Fixes #33680

Should process template literals in all positions where TS support them. Should correctly return full list when ts.preProcessFile is called.

I also tried to write test like https://github.com/microsoft/TypeScript/blob/98cf317005d62a9b275e1f1b37a18b7f5b457e74/tests/cases/fourslash/shims-pp/getPreProcessedFile.ts
but when I use dynamic imports

/// <reference path="fourslash.ts" />
// @module: esnext
// @target: esnext

// @Filename: main.ts
// @ResolveReference: true
//// const a = import(/*1*/`wrong`/*2*/);

goTo.file("main.ts");
verify.numberOfErrorsInCurrentFile(1);
verify.errorExistsBetweenMarkers("1", "2");

I receive 3 errors

Unexpected error(s) found.  Error list is:
  global, message: Cannot find global value 'Promise'.

  from: 0:10, to: 0:25, message: A dynamic import call in ES5/ES3 requires the 'Promise' constructor.  Make sure you have a declaration for the 'Promise' constructor or include 'ES2015' in your `--lib` option.

  from: 0:17, to: 0:24, message: Cannot find module 'wrong'.

Actual number of errors (3) does not match expected number (1)

Where only 3rd error was expected.

Setting module to commonjs or target to es2015 doesn't help.

Do I need to add tests for error reporting on wrong references (3rd error)? Any suggestions how to avoid unexpected errors?

Thanks for the PR! It looks like you've changed 'preProcess.ts' in some way. Please ensure that any changes here don't break consumers with unique project systems such as Visual Studio. Pinging @sheetalkamat, @amcasey, and @minestarks so they are aware of the changes.

I closed/re-opened the PR to re-run tests, just to see whether tests still pass after sitting for 6 months.

[IllusionMH]

Should I rebase on top of master?

[sandersn]

It would be nice -- I didn't know you were still paying attention to this PR @IllusionMH!

[IllusionMH]

Rebased. Sorry for delay - local test/lint took 28mins

I didn't know you were still paying attention to this PR @IllusionMH!

I didn't know when/if it will be reviewed/merged, so decided to avoid unnecessary notification spam on pushes.
Unfortunately there are no notifications for project board moves and I've missed changes few days ago.

(I treat no-notifications as a feature so I can move things around all over the place without spamming people.)

[sandersn]

Everything but node 10 and node 8 on Travis is done, so I'm going to merge this.

[IllusionMH]

Thanks!

Yeah, it's great that there are no labels/project spam all the time for sure :)
