intel/isl: Rename supports_lossless_compression to supports_ccs_e

The term "lossless compression" could potentially mean multisample
color compression, single-sample color compression or HiZ because they
are all lossless.  The term CCS_E, however, has a very precise meaning;
in ISL and is only used to refer to single-sample color compression.
It's also much shorter which is nice.
