DRI3: Add multi-planar and modifier support

Browse source 
Bumping to version 1.2, add support for:
  - querying formats and modifiers supported by the server
  - creating (and receiving) multi-planar buffers
  - creating (and receiving) buffers with modifiers

v2: Fix alignment
v3: Bump to version 1.2 rather than 1.1. The old dri3proto had a '1.1'
    release for non-functional changes, so we avoid that version and
    skip directly to 1.2.
