This will allow further optimizations for shader variants that change
GS outputs (affecting the copy shader), and this is mainly about sharing
optimizations with NGG instead of having a totally separate codepath for
legacy GS.

The samplemask VGPR that we had to pass to the epilog increased VGPR usage
by 1 for all shaders. Do it in the main function by using the mono key
structure, which causes on-demand compilation and stall, but we'll save
the VGPR.

This generally works well.
There are new cases that select Wave32, and there are shader profiles
which adjust that.

It already does compaction, so we just need to load vertex positions
and cull. This was easier than expected.

This uses a C++ template to compute the memcmp size at compile time,
which is important for getting inlined memcmp.
There are 4 different key sizes now:
GE with inlined uniforms: 68 bytes
GE without inlined uniforms: 52 bytes
PS with inlined uniforms: 28 bytes
PS without inlined uniforms: 12 bytes

ps is for the pixel shader, while ge is for VS, TCS, TES, and GS.
si_shader_key: 68 bytes
si_shader_key_ge: 68 bytes
si_shader_key_ps: 28 bytes
The only notable change is that si_shader_select_with_key is changed
to a C++ template. Other changes are trivial.
