Test that createBitmap(65535,65535) throws OOME

Bug: 33846679
Test: this

A Java GIF decoder (e.g. FrameSequence) may attempt to create a large
Bitmap (up to the maximum GIF size of 65535 x 65535). Test that we throw
OOME, which corresponds to the old code when Bitmap pixel memory was
allocated from Java/JNI (instead of creating a null Bitmap and then
throwing a NullPointerException inside createBitmap).
