When CCS compression first came out on Skylake, we referred to it as
"renderbuffer compression", or RBC for short. However, that name has
long since fallen out of favor, and we refer to it as CCS nearly
everywhere.
This patch renames DEBUG_NO_RBC to DEBUG_NO_CCS inside the codebase
for clarity, and adds INTEL_DEBUG=noccs. The legacy INTEL_DEBUG=norbc
name continues to work, because it's one line of code and having both
names makes our lives easier in the interim.

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.

Move all the NIR related debug environmental variables in a single
NIR_DEBUG one.
Use NIR_DEBUG=help to print all the available options.
v2:
- Use a macro to simplify (Marcin, Jason)
- Remove wrong changes (Marcin)
v3 (Marcin):
- Remove rendundant NIR mentioning in option descriptions.
- Unwrap option descriptions.
- Ensure the constant is unsigned.
- Use extern array to remove switch.
v4:
- Add missing kernel shader (Jason).
- Add unlikely() (Marcin).

This adds a new vk_queue_submit object which contains a list of command
buffers as well as wait and signal operations along with a driver hook
which takes a vk_queue and a vk_queue_submit and does the actual submit.
The common code then handles spawning a submit thread if needed, waiting
for timeline points to materialize, dealing with timeline semaphore
emulation via vk_timeline, etc. All the driver sees are vk_queue.submit
calls with fully materialized vk_sync objects which it can wait on
unconditionally.
This implementation takes a page from RADV's book and only ever spawns
the submit thread if it sees a timeline wait on a time point that has
not yet materialized. If this never happens, it calls vk_queue.submit
directly from vkQueueSubmit() and the thread is never spawned.
One other nicety of the new framework is that there is no longer a
distinction, from the driver's PoV, between fences and semaphores. The
fence, if any, is included as just one more signal operation on the
final vk_queue_submit in the batch.

It's a bit on the over-complicated side but the objective is to make the
debug log messages show up in the same thread as the first
VK_ERROR_DEVICE_LOST so we don't massively confuse the app. It's
unknown if this is actually ever a problem but, with submit happening
off on its own thread, logging errors from threads the client doesn't
know about doesn't seem like a massively great plan.

This commit enables NGG culling on all GFX10.3 GPUs by default.
A new debug flag environment variable RADV_DEBUG=nonggc is added to
disable this feature on GPUs where it is enabled by default.
The previous perf test flag RADV_PERFTEST=nggc will not be needed on
GFX10.3 anymore but it can still be used to enable the feature on
GPUs where it isn't on by default.

It seems something went wrong during conversion of this article (or
maybe even before in the HTML version), where every header after the
"Gallium environment variables" header was nested below it.
That's clearly not what's meant here, so let's fix that.
This makes the toctree make a bit more sense for this article.

The support for color-indexed rendering was removed from mesa all the
way back in 2010, in commit 81fe9949ef ("mesa/xlib: Remove support for
color-index rendering").
So let's drop it from our documentation as well. This environment
variable does nothing.
