zink: add a suballocator

this is an aux/pipebuffer implementation borrowing heavily from the
one in radeonsi. it currently has the following limitations, which
will be resolved in a followup series:
* 32bit address space still explodes
* swapchain images still have separate memory handling

performance in games like Tomb Raider has been observed to increase by
over 1000%

SQUASHED: simplify get_memory_type_index()

now that the heaps are enumerated, this can be reduced to a simple
array index with a fallback
