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
