Migrate robolectric tests to junit tests

This change do the 2 things:

1. Add new junit tests files which replace robolectric
   RobolectricTestRunner & RuntimeEnvironment with
   AndroidX objects without problem.
2. Remove the robolectric test files which have it's new junit files.

This change migrate 103 files, there are still 1209
files to go.

Bug: 174728471
Test: atest
      make RunSettingsRoboTests
Change-Id: I15ed3f4745b85862f720aabbf710ce1475aced93
