ReinUsesLisp 35df1d1864 vk_staging_buffer_pool: Add stream buffer for small uploads
This uses a ring buffer similar to OpenGL's stream buffer for small
uploads. This stops us from allocating several small buffers, reducing
memory fragmentation and cache locality.

It uses dedicated allocations when possible.
