Fix content upside down when call OffscreenCanvas's commit

The reason that the content is upside down is that we have a flag called
yflipped and it is always false. In the case of GPU compositing, this flag
should be true.

This CL also updates pixel tests for WebGL's commit, such that instead
of drawing a uniform color square, we draw a white triangle on a green
background.

Remove some failure entries in pixel_expectations.py

In our previous CL: https://codereview.chromium.org/2417773003/, we
changed the contents of some pixel tests and labeled them failure. The
above CL has been picked up by most of the GPU bots, I have checked all
the generated reference images and they are all fine. Some of the FYI
bots (android ones) are purple for a while, so I will keep an eye on
those bots once this CL is in.
