Marek Olšák df6380ddc9 amd: implement conformant TRUNC_COORD behavior for gfx11 ...

For testing, the conformant behavior can be enabled by setting
conformant_trunc_coord to true manually and running this to enable
the conformant behavior in hw:
    umr -w *.*.regTA_CNTL2 0x40000

The layer index rounding and TRUNC_COORD resetting workarounds can disabled
in the shader compiler.
