st/mesa: accelerate glGetTexImage for all formats using a blit
This commit allows using glGetTexImage during rendering and still
maintain interactive framerates.
This improves performance of WarCraft 3 under Wine. The framerate is
improved
from 25 fps to 39 fps in the main menu, and from 0.5 fps to 32 fps in the
game.
v2: fix choosing the format for decompression
