dri_interface: add interface for EGL_EXT_surface_compression

Browse Source 
This adds two new methods for the image extension (version 22):

 - Query the supported compression bitrates for a given format
 - Query the modifiers associated with a given format and bitrate

The interface user can then use createImageWithModifiers to
actually allocate the fixed-rate compressed image. When the default
bitrate is requested, one can query the image for the
__DRI_IMAGE_ATTRIB_COMPRESSION_RATE attribute to determine the
compression rate that was actually used.
