Update support library dependency for coreTestApp
Update support library dependency for coreTestApp

Fix the coreTestApp crash on some specific test devices
After testing on some devices, the appcompat:1.3.0 seems
more stable than the latest build. And we can remove the
androidx.activity & androidx.fragment dependency since they
are already used in the appcompat.

Bug: 192899704
Test: manually run ToggleButtonUITest & BasicUITest on lab devices.
