  To: igt-dev

Blitter commands may have different properties depending on the
platform. Add a new field to blt_tiling_info struct to describe
properties of the commands. Update definitions of block-copy on
DG2 and beyond to show the differences. Add helpers that check
if a platform uses an extended version of the block-copy command
or supports compression. Update gem_ccs test to use these
functions.
