dri: introduce dmabuf format modifier related handles

Browse source 
these allow dmabuf import with modifiers, and supported format and
modifier queries, which are used to implement
EGL_EXT_image_dma_buf_import_modifiers.

v2:
- squash dmabuf queries into DRIimage version 15 (Jason Ekstrand).
- add external_only param to queryDmaBufModifiers (Emil, Daniel Stone)
- pass a single modifier form createImageFromDmaBufs2 since all planes have
the same modifier (Jason Ekstrand)
