Rotate markerview (#6640)

* [android] - MarkerView rotation bug, limit degrees from 0 to 360 while creating a MarkerView

* update MarkerView#setRotation to limit input from 0 - 360 degrees, calculates difference in angle and animates rotation by a certain amount instead of animating to a value. Exposed new AnimatorUtils#animateRotationTo. Integrated into MarkerViewManager. Cleanup some unused imports. Updated javadoc.

* updated MarkerViewActivity in test application to test for regressions.

* added tests to validate changes to MarkerView#setRotate
