Changed Analog Clock to be a frame layout

Bug: 30492908

Rotating a drawable on Android M causes it to become progressively
fuzzier and then disappear at rotations of 90 and 270 degrees. To
remedy this, the Analog Clock implementation has been changed to
use rotated views versus rotated drawables.
