We set the number of task shader ring entries in radv_device
based on the generous assumption that each CU can run task/mesh
shaders with maximum occupancy.

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.

This is going to be used by both task and mesh shaders for

Task shaders store their output payload to VRAM where mesh
shaders read from. There are two ring buffers:
1. Draw ring: this is where mesh dispatch sizes and
the ready bit are stored.
2. Payload ring: this is where the optional payload
is stored (up to 16K per task workgroup).

This pattern pops up a bunch and the semantics of nir_channels() aren't
very convenient much of the time. Let's add a nir_trim_vector() which
matches nir_pad_vector().

This takes the buffer ptrs out of the struct, so they can be memset
separately and optimises the memset to be minimal for them.
Removing them from the struct avoids having to loop to clear them.

Additionally, don't create the continue preamble when we can use
