gallium: introduce 'pipe_screen' for context-independent functions
This will allow creating textures before a rendering context exists, for example. Only implemented in i915 driver for now. i915pipe->texture_create() just dispatches through to the i915screen->texture_create() to avoid state tracker changes for now.
