Reland "Use ImageDecoder for NinePatchDrawable and BitmapDrawable"

This reverts commit ac9c8f7c.

Bug: 73083791
Bug: 73364985

Don't scale NinePatchDrawable if bitmap has no density (including fix
for 73364985).
Fixed bugs around density and input streams.

Update PointerIcon to account for the fact that BitmapDrawable no longer
scales its Bitmap up at decode time. PointerIcon now handles the
scaling. This is necessary because PointerIcon never draws its Bitmap.
Instead, native code uses the Bitmap's internal SkBitmap without
accounting for density.
