intel/isl: Allow CCS_E on more formats

Browse source 
Now that BLORP supports copies on everything except R11G11B10_FLOAT,
we should be able to support CCS_E those formats.

/* For simplicity, only report that a format supports CCS_E if blorp can
* perform bit-for-bit copies with an image of that format while compressed.
* This allows ISL users to avoid having to resolve the image before
* performing such a copy. We may want to change this behavior in the

*
* The following formats have no equivalent UINT format. Given how
* blorp_copy currently works, bit-for-bit copy operations are not possible
* without an intermediate resolve.
* Unfortunately, R11G11B10_FLOAT is in a compression class of its own and
* there is no way to copy to/from it which doesn't potentially loose data
* if one of the bit patterns being copied isn't valid finite floats.
