Stub out Trusted Types interfaces (#36355)

Browse source 
Some methods are implemented fully, while others are implemented
partly. With these implementations, there are no observed crashes
when running the trusted-types web-platform-tests.

Most notably, the tests/wpt/tests/trusted-types/idlharness.window.js
is now fully passing.

Part of #36258
