radeonsi: use SPI_SHADER_COL_FORMAT fields instead of export_16bpc
This does change the behavior slightly:
If a shader writes COLOR[i] and that color buffer isn't bound,
the shader will export MRT_NULL instead and discard the IR tree that
calculates the output. The only exception is alpha-to-coverage, which
requires an alpha export.
v2: - update a comment about 16BPC
- account for MRTZ when when fixing alpha-test/kill
