intel/isl: Allow creation of 1-D compressed textures
Compressed 1-D textures are not well-defined thing in either GL or Vulkan.
However, auxiliary surfaces are treated as compressed textures in ISL and
we can do HiZ and CCS with 1-D so we need to be able to create them. In
order to prevent actually using them (the docs say no), we assert in the
state setup code.
