d54c8a47c6 meson: avoid using deprecated build_root() method 
The meson.build_root() method has been deprecated, so let's switch to
meson.project_build_root(), which usually means the same thing. The case
where it doesn't do the same thing is if Mesa is a subproject to some
other project, but in that case I believe we want the build root of Mesa,
not of the parent project anyway.

6872f8d861 aco/gfx11: allow true 16-bit instructions to access v128+ 
It looks like the LLVM assembler promotes true 16-bit instructions to VOP3
in this case.

No fossil-db changes.

254b178d5b aco: disallow SGPRS/constants with interpolation instructions 
https://reviews.llvm.org/D137575

The VINTRP format cannot encode anything except VGPRs.

Reading VINTERPInstructions.td, looks like it's the same for GFX11.

No fossil-db changes.

9b6ab40b3b aco: improve do_pack_2x16() with zero constants 
We can skip the v_or_b32 or use an instruction smaller than
v_alignbyte_b32.
