Remove glPixelStore GL_PACK_IMAGE_HEIGHT calls. 

This enum is unsupported in OpenGL ES. If this is actually a problem
for WebGPU, we may need to add validation for WebGPU-compat to prevent
reading from a texture to a buffer with a different image stride. I'm not sure
if that's currently possible, and it doesn't seem to be covered by tests.
