David Anderson f31f64f5a2 vram: refactor MemArbiter into separate arbiters 
Rather than hardcode one architecture for GARY, the arbiters
are now split and can be allocated per-port. The arbiter interface
includes plumbing so that one arbiter can propagate a write conflict
to another, so it can still implement multi-port arbitration as long
as every client is statically allocated to one port.

David Anderson ab20db44f4 vram: rename MemoryArbiter to something shorter 
As I implement the whole transaction-level modeling thing with
arbitration, the interface names are getting longer and longer.
