052a758cfb kraid/isa: Add a simple XML parser 
The xml crate doesn't provide a DOM but it makes everything easier to
have one so let's hand-roll a super simple DOM for the ISA XML.

99dd4d269f kraid: Add the start of encoder code-gen 
This is structured both as a proc macro and as a stand-alone executable.
This gives us options for how we want to actually dispatch it.

d5c4fb763a radv: fix an inefficiency where the ANCILLARY PS VGPR was enabled but unused 
This was probably enabled because sample_mask_in lowering used sample_id.
Now that the lowering is done before shader info gathering, this
inefficiency can be removed.
