USE_PUSH_DESCRIPTORS may be misleading since it would be set even when

The packed descriptor index is no longer needed, and causes issues in

For correctness, we will need to defer any initial resource state
handling to the queue timeline. Here, we will build an UNDEFINED ->
common layout barrier if (and only if):
- The resource is marked to care about initial layout transition.
- We are the first queue thread to observe that initial_transition
member is 1 (atomic exchange).
- The first use of the resource was not marked to be a discard.
E.g., if the first use of the resource is an alias barrier, we must
not emit an early barrier. The only we should do here is to clear the
initial_transition member, and leave it like that.
A command list maintains a list of d3d12_resources which *might* need a
transition. For the first frame a resource is used (or so), it will not
have the flag cleared yet, so multiple command lists might add the
d3d12_resource to its own transition list. This is fine, as the queue
will resolve it.
If multiple queues see the same initial transition, there might be
shenanigans, but the application must ensure there is either a
submission boundary or fence boundary between the uses. Any initial
layout transition will only be submitted after a Wait() is observed, as
submission of the transition command buffer will be in-order with other
submissions.

D3D12 supports out-of-order signal and wait. So does Vulkan timeline
semaphores. However, in Vulkan we don't have an infinite amount of
virtual queues. We must potentially map multiple D3D12 queues on top of
Vulkan, which might lead to a deadlock when app attempts to
wait-before-signal if the two queues are mapped to the same physical
Vulkan queue.
In order to solve this, we need to hold back submissions until we know
it is safe to do so. To make this work in practice as simply as possible, each
ID3D12CommandQueue has its own submission thread, which will block on an
ID3D12Fence's pending timeline value for a Wait command. The main reason to use a
submission thread is that resolving this directly in
ID3D12CommandQueue::Signal is extremely tricky and potentially
needs recursively locking queues and fences.
Note that we only block on the pending wait value, not the actual wait
value, so there is no real CPU <-> GPU synchronization here. In the
common case, no submission thread will block.
The added benefit is that submits are async now, so main thread CPU
overhead might slightly decrease.
To play nice with DXGI swapchain, the external entry point for acquiring
the Vulkan queue needs to drain the submission thread and lock it to ensure
submissions happen in order.
Fixes hangs in The Division 1, which makes use of this D3D12 feature.
