Add support for TRUSTED_TYPES when using Wasm Workers

[jriv01]

This change allows usage of Trusted Types compatible wrappers for Wasm Workers when TRUSTED_TYPES is defined.

Similar behavior has already been implemented in libpthread.js, so the changes here are based off of & exhibit the same logic used for Trusted Types & pthread compatibility.

I guess we need some kind of test for this?

We do have an existing test for TRUSTED_TYPES in test/test_other.py. Can perhaps add a variation to one of the existing WASM_WORKERS tests there, that adds this.

When you say add a variation that matches the existing TRUSTED_TYPES test, did you mean using @paramaterized?

emscripten/test/test_other.py

Lines 13161 to 13165 in 88ffcb9

	@parameterized({
	'': [[]],
	'trusted': [['-sTRUSTED_TYPES']]
	})
	def test_pthread_export_es6(self, args):

So something like

   @parameterized({ 
     '': [[]], 
     'trusted': [['-sTRUSTED_TYPES']] 
   }) 
   def test_wasm_worker_hello(self):
     ...

Yup that looks about right.

It seems like there's still a CI failing, any idea what may be causing that?

I see it says Test expectations are out-of-date on the PR branch. You can run './tools/maint/rebaseline_tests.py' to create a commit updating the expectations. but I already did that at commit c6305cf

I think maybe you should try reverting test/other/codesize/test_codesize_files_wasmfs.size. I don't see how this change could have changed the size of that test.

There seems to be some new failures despite not changing anything since 43a04dc.

Any idea what might be happening here? I see that f391a0d addresses the test_fs_js_api_wasmfs failure under test-wasm64-4gb so syncing this branch should fix that, but there's two separate failing tests in test-wasm64.
