Disable menu-related translate bubble tests on Mac

NSMenus on Mac block in a nested run-loop, so any tests that open a menu
and try to do things to it or sense things on it either:
- Succeed by accident because of a race condition with app activations
- Block until the menu or another window is interacted with

Disabling these until we've either been able to make NSMenus asynchronous
to match views expectations, or found a way to test this functionality a
different way.

|AlwaysTranslateLanguageMenuItem| has an additional problem: pressing a
button halfway through closes the bubble, but on non-Mac platforms, the
test can continue due to asynchronous window closing. On Mac, the window's
content view is removed as soon as closing begins. We'll probably need
to address this by breaking it up into multiple tests and creating a way
to sense the state without relying on an object owned by the closing
bubble.

This might have been fixed (or largely fixed) by <https://chromium-review.googlesource.com/c/chromium/src/+/998016> since all MacViews menus are now Views menus.
