gpu: Optimize and cleanup code used for CHROMIUM_copy_texture.
When source target and destination target is GL_TEXTURE_2D, we can use
glCopyTexImage2D() directly. It avoids gl state changes, program binding and
drawing call.
|dest_target| of DoCopyTexture() is always GL_TEXTURE_2D, so remove the
redundant argument.
Perf data are as follows:
Linux (Intel IvyBridge i7-3520M): 16 us vs 6 us -> 260% faster
Android (Nexus 5): 331.8 us vs 252.7 us -> 31% faster
