counterOffset was just ignored and nobody noticed (missing VKCTS
coverage).
VGT_STRMOUT_DRAW_OPAQUE_OFFSET will do the computation in hw for us.

Rename the drirc and call it radv_disable_dedicated_sparse_queue instead,
since normal queues support sparse now anyway.
Keep the workaround for existing known games, since they might not
expect a separate SPARSE queue to pop up.

Forcing a dedicated sparse queue is problematic in real-world scenarios.
In the current implicit sync world for sparse updates, we can rely on
submission order.
For use cases where an application can take advantage of the separate
sparse queue to do "async" updates, the existing implementation works
well, but problems arise when trying to implement D3D-style submission
ordering. E.g., when a game does sparse on a graphics or compute queue,
we need to guarantee that previous submissions, sparse update and future
submissions are properly ordered.
The Vulkan way of implementing this is to:
- Signal graphics queue to timeline N (i.e. last submission made)
- Wait on timeline N on the sparse queue
- Do sparse updates
- Signal timeline N + 1 on sparse queue
- Wait for timeline N + 1 on graphics queue (can be deferred until next
graphics submit)
This causes an unavoidable bubble in GPU execution, since the
existing sparse queue ends up doing:
- Wait pending signal. The implication here is that all previous GPU
work must have been submitted.
- Do VM operations on CPU timeline
- Wait for semaphores to signal (this is required for signal ordering)
- ... GPU is meanwhile stalling in a bubble due to GPU -> CPU -> GPU roundtrip.
- Signal semaphore on CPU (unblocks GPU work)
Letting the GPU go idle here is not great, and we can be screwed over by bad thread scheduling.
Another knock-on effect is that the graphics queue is now forced into
using a thread for submissions. This is because when the graphics queue
wants to wait for timeline N + 1, the sparse queue may not have
signalled the timeline yet on CPU, so effectively, we have created a
wait-before-signal situation internally in RADV. Throwing another thread
under the bus is not great either.
Just letting the queue in question support sparse binding solves all
these issues and I don't see a path forward where the D3D use case can
be solved in a separate queue world.
It is also friendlier to the ecosystem at large. RADV is the only driver
I know of that insists on separate sparse queues and multiple games
assume that graphics queue can support sparse.

The radv-stoney-angle-full was unintentionally inheriting the fraction
from the pre-merge job.
Also use the correct manual rules definition while we're here, and use
consistent naming for the restricted rules.

This switches to disk_cache instead of our own mechanism which only
stored meta shaders when the logical was destroyed.
Meta shaders are still stored separately from the application shaders
because they are common to all applications on a given GPU/Mesa version.
The default cache is 32MiB which should be large enough.
This fixes massive stuttering in FF7 Rebirth but all apps are
technically affected.

I think this was broken as there might be a store_output with
less than 4 components to a location that shouldn't be smoothed
anyway (i.e. not the first one).
nir_lower_poly_line_smooth now handles the case where the first location
doesn't have 4 components.
