Enable "gn check" for //third_party/blink/renderer/modules

* Add missing dependencies

* Move html_media_test_helper.* from html:unit_tests to
  core:unit_test_support
* Move fake_canvas_resource_host.h from platform:unit_tests to
  platform:test_support
  Because they are used in modules:unit_tests, and it can't depend on
  html:unit_tests and platform:unit_tests.

This CL has no behavior changes.
