Revert "Reapply "Skip compressed image_copy tests in Compatibility mode. (#3140)" (#3161)"

This reverts commit 0e06340.

These tests test writeBuffer, copyBufferToTexture, and copyTextureToBuffer
as it says at the top of the file. They should not have been disabled for
textures that don't support copyTextureToBuffer. For those cases they
use rendering compare results.
