From: Conor McCarthy <cmccarthy(a)codeweavers.com>
D3D12 supports signalling a fence to a lower value, while Vulkan timeline
semaphores do not. On the GPU side this is handled by simply submitting
the signal anyway, if a test for this passes on device creation, because
working around this is impractical. For CPU signals the Vulkan semaphore
is replaced with a new one at the lower value only if no waits and/or
signals are pending on the GPU. Otherwise, a fixme is emitted.
Partly based on a vkd3d-proton patch by Hans-Kristian Arntzen (not
including the handling of lower fence values).
The old implementation is used if KHR_timeline_semaphore is not
available or GPU signals do not work for a lower value.

This supersedes patch 230633.
v4:
- Fix the (trivial) merge conflict with patch 230641.
- Simplify setting "device->use_timeline_semaphores".
