Make --no-window-animation flag apply to animators, too

There is a flag for 'adb shell am instrument' that disables animations, which
is useful for testing (if you want to, for example, disable animations to speed
up tests or remove animation-caused side-effects as a factor). But only the
pre-honeycomb animations (window transitions and window animations) were listening
to this flag. This change makes animators listen as well, so all three duration scale
settings are affected.

Bug: 32072407  --no_window_animation ADB arg should set all animation scales to 0.0f
Test: manual. Ran frameworks APCT tests with --no_window_animation and verified
that all three types of animations had their duration scales set to 0 for the
duration of the tests.
