Removed hidden mutable APIs from PorterDuffColorFilter

Removed PorterDuffColorFilter#setColor and PorterDuffColorFilter#setMode
as the public facing ColorFilter API is immutable. These framework
internal APIs were causing issues with Drawables as updates to state of
the ColorFilter would not be propagated up to the Drawable to cause an
invalidation.

Fixes: 77723600
Test: Ran atest on SystemUITest and CtsGraphicsTest modules
