Add TestKeyboardControllerObserver (Take 2)

Original CL: https://chromium-review.googlesource.com/c/1343524
FIX: Minor change to exo_unittests BUILD.gn file

Add TestKeyboardControllerObserver for ash keyboard unit tests

This also includes some cleanup of the BUILD.gn files.

Currently TestKeyboardControllerObserver is only needed by
AshKeyboardControllerUnitTests, but will be required by any tests
affecting the keyboard with SingleProcessMash once enabled.
