OpenGL: Make use of persistent buffer maps in buffer cache downloads

Persistent buffer maps were already used by the texture cache, this extends their usage for the buffer cache.

In my testing, using the memory maps for uploads was slower than the existing "ImmediateUpload" path, so the memory map usage is limited to downloads for the time being.
