The additional usage bits added for rgba8 and rgb565 are not needed as
those are conditionally added based on the consumer side of the Android
surface (e.g. display, encoder, etc).

Similar to nir_lower_alu_width(), the callback can return the
desired number of components for a phi, or 0 for no lowering.
The previous behavior of nir_lower_phis_to_scalar() with lower_all=true
can be elicited via nir_lower_all_phis_to_scalar() while the previous
behavior with lower_all=false now corresponds to nir_lower_phis_to_scalar()
with NULL callback.

Add a new field userq_num_hqds to drm_amdgpu_info_hw_ip to expose the
number of available hardware queue descriptors (HQDs) for user queues.
This allows userspace to query the maximum number of user queues that
can be created for a particular IP block.

v3: rename num_userqs to num_queue_slots

From the Vulkan spec:
`If pColorAttachmentLocations is NULL, it is
equivalent to setting each element to its index
within the array.`
Use similar logic to what we do in
CmdSetRenderingInputAttachmentIndices to handle
this behaviour properly.

This changes legacy GS outputs to use the same logic as NGG GS.
It enables the same optimizations that NGG has such as forwarding
constant GS output components to the GS copy shader at compile time.
ac_nir_gs_output_info is removed.
GS output info is no longer passed to ac_nir_lower_legacy_gs and
ac_nir_create_gs_copy_shader separately.
ac_nir_lower_legacy_gs now gathers ac_nir_prerast_out, generates GSVS ring
stores, and also generates the GS copy shader with GSVS ring loads.

This is a cleanup.
Old gs LDS layout: [es outputs][gs outputs][scratch]
Old nogs LDS layout: [xfb/cull][scratch]
New gs LDS layout: [es outputs][scratch|gs outputs]
New nogs LDS layout: [scratch|xfb/cull]
The LDS scratch is moved to the beginning of the preceding buffer in LDS,
while the addresses in that LDS buffer are offset by the scratch size.
It effectively merges the LDS scratch with the preceding buffer in LDS.
Thanks to that, we no longer need the ngg_scratch ABI and the offset
in a user SGPR.
The lowering passes now return the LDS scratch size, which is used
by the drivers to determine the final LDS size.
The ngg_lds_layout SGPR is now unused without GS in RADV.

We incorrectly used it to determine whether the shader should cull, which
luckily had no effect because it wasn't used everywhere.
cull_clipdist_mask should be used instead, which also reflects whether
clip planes are enabled in GL.
clip_cull_dist_mask is renamed to export_clipdist_mask to make it clear.

This looks like a hw bug on GFX10.3-GFX11.5 because RB+ seems to only
work as expected when all channels (RGBA) are written. With that format,
RGB channels must be all set or unset but setting the A channel is
legal so far.
This will reduce rendering performance with that format but it's the
less intrusive solution for now. This might be revisited in the near
future, also with more VKCTS coverage.
This has been tested and verified on GFX10.3 (NAVI21) and GFX11
(NAVI31) and GFX12 (NAVI48), unfortunately I don't have GFX11.5 but
let's assume it's broken there too.

This switches the code to the new slot offsets from ac_nir_prerast_out
instead of using a prefix bitmask over outputs_written.
The LDS layout no longer includes these:
- GS: output components that are not written by GS
- VS/TES+XFB: output components that are not written by XFB
- VS/TES+XFB: slots that are not written by XFB (this could be significant)
This is also a cleanup because it unduplicates the bitcounts.
