The PS epilog would be a "normal" compiled shader using RA, etc. It
will declare up to 8x4 VGPRs for all color exports.

The main FS would have to jump to the PC of the PS epilog. Given that
shaders are allocated in the 32-bit addr space, one user SGPR is fine.

Mostly the same as for compute shaders, but with a few extras:
task_ring_offsets:
Same as what ring_offsets is to graphics shaders.
Contains an address that points to a buffer that contains
the ring buffer descriptors.
task_ring_entry:
Index that can be used to address the draw and payload rings.
draw_id:
Same meaning as in graphics shaders.
task_ib_addr/task_ib_stride:
Indirect buffer address and stride from the draw calls.
These are used to emulate the firstTask feature of NV_mesh_shader.

The shader locations are now directly stored in radv_shader_args which
makes sense because they are tied to the arguments. The locations are
then copied to radv_shader_info but they will be moved into a new
