Primitive export used the gs_accepted variable after culling,
so we overwrote this variable after vertex compaction to make
sure not to hang the GPU.
This had an unintended side effect when storing the primitive ID
to LDS on GS threads: the LDS store was done even on threads whose
triangle was culled; potentially causing issues.
As a fix, create a separate boolean variable that remembers
which invocations need to export a primitive; and don't store
the primitive ID to LDS when gs_accepted is false.

This information was wrong in some places, let's fix it now.
GFX6:
The GPU has 64KB LDS, but only 32KB is usable by a workgroup.
NGG:
There was some misinformation about NGG only being able to
address 32 KB LDS, it turns out this is actually not true
and it can address the full 64K.

This commit consolidates the queue submit code paths into one.
Now we always allocate BOs for every CS, but when IBs aren't
allowed, we simply submit every BO to the kernel.
A microbenchmark done by Bas indicated that submitting more IBs to
the kernel only adds a negligible overhead. Additionally, this
allows us to stop copying the command buffer contents in system
memory and get rid of a lot of legacy code.
In order to be able to submit every BO, we make sure to add the
last BO to the old_ib_buffers array on cs_finalize. This also
necessitates some changes in cs_execute_secondary and other
functions.

This will still make it so that RADV_DEBUG=hang will only submit
one command buffer at a time, but otherwise let's pass all CS
objects into one submission and let the winsys split them if
necessary.
The winsys can do a better job at splitting them because
radv_queue has no knowledge of IBs and ignores chaining in the
splitting logic.

Currently, radv_queue already splits submissions but we want to
change this and be able to split them in the winsys code as well.
Necessary because we want to split based on number of actual
IBs not number of command buffers, but radv_queue is not
aware of IBs.
Note that this commit does not actually take this new split into
use yet, that will be done in a following commit when it is ready,
this is why we set the max IB count higher than radv_queue here.
This commit is the first step in making "fallback" the default and
only submission code path.

Originally, we could omit generating the continue preamble when

Though they should also be invalidated after executing secondaries,
otherwise nothing is invalidated if the same pipeline is bind to the

Replaces the RADV pipeline cache with an implementation
based on the common vk_pipeline_cache.
We use a dual-layer approach with two types of cache entries.
1. radv_shader:
- serialized as radv_shader_binary
- uses SHA1 of the binary as key
2. radv_pipeline_cache_object:
- contains pointers to associated radv_shaders
- serialized as list of SHA1
- uses the pipeline hash as key
In combination with single-file disk-cache, this reduces the cache size by ~60%.

This function takes a radv_shader_binary and writes it to the
disk cache before creating and returning a radv_shader cache entry.
The key of the cache entry is the full SHA1 hash of the binary.
This way, we will be able to deduplicate identical shaders.
