May in some cases improve performance when under memory pressure:
If a dedicated allocation is preferred, but the alloaction fails,
try to allocate memory from an already allocated chunk instead
of falling back to system memory right away.
The priority defines the importance of any given allocation being
resident in device-local memory rather than system memory, with
values between 0 (low) and 1 (high).
Suballocations will only work on chunks with the requested priority.
This ensures that high-priority allocations are reserved solely for
high-priority resources, and that high-priority resources will be
allocated from a high-priority memory chunk.
Vulkan does not support non-identity swizzles for image views that are
used for rendering, but we have to keep the information around in order
to support rendering to swizzled image formats.
Rather than creating just one image view per DxvkImageView, we create
views for all compatible types in an attempt to work around game bugs
in Diablo 3, Far Cry 5, Nier Automata, Dishonored 2, Trackmania etc.,
which bind incompatible resource views to some resource slots.
