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.

Not doing this for APUs because spilling is quite likely, due to
overall VRAM pressure.
Also adding a flag to disable for performance debugging.
Finally adds some memset for places where we depended on the memory
being initialized to zero, which we won't get with VRAM anymore.
(I think these places should stop depending on it since it hides
issues with executing the cmdbuffer multiple times, but this
preserves behavior)
