AOSP/Messaging - Changes to make unit tests to run and pass.

+ Added missing androix libraries to LOCAL_STATIC_ANDROID_LIBRARIES.
+ Added keep class statements for androidx and messaging classes.
+ Deleted Assert.isEngBuild call (this package is the last user of that method).
+ Added import statements for androidx classes.

Test: manual - Tested the messaging UI. Ran the following tests on Pixel phone.
