gallium: Set all state via cso_context in blit/gen_mipmap utils.

cso_restore_* functions are implemented on top of cso_set_*, therefore
they require full knowledge of the current pipe state to work correctly.
Directly calling pipe's set_*_state functions will lead to undefined state.

Also save and restore shaders.
