  Revert "Metal: Optimized BufferSubData per device"
  
  This reverts commit 968041b54770af8917001d8fe9b52a881cfed0b2.
  
  Includes the following patches:
  
  git revert -n 995db1f66bcf87fc9e47d908fb2a885e810d2567 \
    9a6c90c8f802b4d107a081bfccaf4be007e7af54 \

    968041b54770af8917001d8fe9b52a881cfed0b2
  
  Several conflicts with top-of-tree were resolved during this revert.
  
  The aim is to reland this with additional code which will reduce the
  amount of excess buffer memory allocated, and release the resources
  associated with temporary buffer allocations.
