intel/isl: Add an isl_swizzle structure and use it for isl_view swizzles

Browse Source 
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.
