  Reland "Metal: Optimized BufferSubData per device"
  
  This reverts commit ee64836f702332adaca58d9f452063a04b2da955 ,
  relanding the patch stack described there.
  
  Between patchsets 1 and 5:
  
  - The shadow buffer allocation has been replaced with a multimap of
    precisely-sized buffers, rather than rounding up buffer sizes.
  
  - Garbage collection of shadow buffers is triggered in three situations:
  
    - A certain number of context switches have occurred; this number
      was hand-tuned to avoid GC every frame.
  
    - A certain number of command buffer submissions has occurred; this
      number was hand-tuned to GC no more often than every few seconds
      on representative workloads.
  
    - The total size of the allocated shadow buffers is more than 1 MB,
      and either more than twice the size at the last garbage
      collection, or 64 MB more than at the last garbage collection. In
      this case, aggressive GC is performed in order to reclaim shadow
      buffers more quickly.
  
  Performance before and after these changes appears identical on
  microbenchmarks. On one Figma test case, comparing GPU memory
  allocated inside the BufferManager, peak consumption is decreased by
  over 75%, and steady-state consumption decreases by over 88%.
  
  Patchset 6 adds a needed workaround for a bug in the
  AMDMTLBronzeDriver affecting uploads of client-side data, and
  therefore some dEQP tests. It also streamlines the aggressive GC.
