dri3: Add multi-planar/modifier buffer requests

Initial implementation for DRI3 v1.1. Only the DRI3 implementation
is there, backends need to implement the proper hooks.

Version is still set to 1.0 so clients shouldn't use the new
requests yet.

v2: Use depth/bpp instead of DRM formats in requests

v3: Remove DMA fence requests from v1.1
    Add screen/drawable modifier sets

v4: Free array returned by 'get_drawable_modifiers()'

v5: Fix FD leak
