We don't plan to support NV_mesh_shader officially on RADV,
because it performs poorly on AMD hardware. However, we are
implementing this extension to get some experience with mesh
shader technology.
Users should not rely on this support because we are going
to remove it if/when a potential cross-vendor extension appears.

The NV indirect command buffer format is not supported by
the hardware, so we have to emit several copy packets to
make it work.
Otherwise it works by emulating the number of launched
MS workgroups by setting the number of "input vertices".

Generic per-primitive outputs:
They work similarly to other NGG outputs.
In the ISA they are param export instructions that are executed
on the primitive threads. These per-primitive params must be
sorted last among both mesh shader outputs and pixel shader inputs.
PS can read these inputs using the same old VINTRP instructions.
They use the same amount of LDS space as per-vertex PS inputs.
Special per-primitive outputs:
The VRS rate x, y, viewport and layer are special per-primitive
outputs which must go to the second channel of the primitive
export instruction, which is enabled by EN_PRIM_PAYLOAD.
If the PS wants to read these, they must also be exported as
a generic param.

Use firstMipIdInTail directly from addrlib which calculated this
in a different way:
Original way: either dimension size of mipmap should be less than
the tile size.
Addrlib way: all dimesion size of the mipmap should be less than
the tile size and at lest one dimension size should be less than
half of the tile size, so that all following mip levels can fit
in one tile and any commit for level in the mip tail also commit
for all levels in mip tail.
Theoretically either way is OK but addrlib way needs less care
about the mip tail commit and better align with the true memory
layout given by itself.

(127.0f / 255.0f). This CB feature is GFX9+ only.
