The result of this calculation goes into an fma() in the shader and we
would like it to be as precise as possible. The division in particular
was a source of imprecision whenever dst1 - dst0 was not a power of two.
This prevents regressions in some of the new Vulkan CTS tests for blitting
using a filtering of NEAREST.

While it can be useful, the field has substantial limtations. In
particular, the bittom 2 or 3 bits is missing so your offset always has to
be a multiple of 4 or 8. While surface alignments usually work out to make
this ok, when you start trying to fake compressed surfaces as uncompressed
(which we will want to do) this falls apart. The easiest solution is to
simply align all offsets to a tile boundary and munge the regions we're
copying to account for the intratile offset.

The convert_to_single_slice operation is *mostly* idempotent. The only
non-repeatable thing it does is that, when it sets the intratile offset
fields, it just overwrites them instead of doing a += operation. This is
supposed to be ok because we have an early return at the top that should
make it bail of the surface is already a single slice. Unfortunately, the
if condition has been broken ever since it was first added in 96fa98c18.
This commit fixes the condition and adds an assert to ensure we don't stomp
any non-zero intratile offsets.

If we use the view format, it may be an uncompressed view of a compressed
image which throws things off. Since we're computing offsets of images, we
want the actual surface offset anyway.

This should be more compact than the enum isl_channel_select[4] that we
were using before. It's also very convenient because we already had such a
structure in the Vulkan driver we just needed to pull it over.

At this point, blorp is completely driver agnostic and can be safely moved
into its own folder. Soon, we hope to start using it for doing blits in
the Vulkan driver.
