Subject: [PATCH] [dxvk] Reduce context staging buffer size to 4 MiB

Same idea as before, just create a temporary buffer for larger resources.

This can avoid frequent Vulkan memory allocations and deallocations since
many small buffers are more likely to fit into a single memory chunk than
a small number of large buffers, thus reducing the overall memory footprint.
