intel: Rename a RenderCompressionFormat field

intel: Rename a RenderCompressionFormat field

The name of the bit field is CompressionFormat. The format subsections
of the field specify the alternate names of RenderCompressionFormat or
MediaCompressionFormat depending on the compression type.

We're going to start programming this field for media compression, so
we'd like to use either the bit field name or a new
MediaCompressionFormat field. Either option seems fine, so we go with
the first.
