vkd3d: Use Vulkan timeline semaphores for D3D12 fences.

Browse Source 
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.
