Override the SetFilterBitmap and IsFilterBitmap functions for AnimatedImageDrawable API
This change in Skia (https://skia-review.googlesource.com/c/skia/+/909816) makes it so that the default sampling method for animated image drawables is linear sampling. This CL implements these drawable API's (https://developer.android.com/reference/android/graphics/drawable/Drawable#setFilterBitmap(boolean)) so that the user can choose to use nearest neighbor sampling if they want pixel perfect scaling.
