Reland: mus: Add views_mus_interactive_ui_tests target

Previous attempt had a size_t to int warning on Windows, which was suppressed in chrome's interactive_ui_tests but not this new target. See https://codereview.chromium.org/1972363002/

* Run widget_interactive_uitests.cc in the new target.
* Added a shared "test_support" target in ui/views/mus.
* Pull ViewsMusTestSuite into its own file so I can share it.
* Also make ViewsTestBase::IsMus static so I can call it before the
  PlatformTestHelper is initialized.
* Disable a bunch of tests that fail on mus (I filed bugs for them).
* Fix an unnecessary size_t to int conversion
