  Add buffer serialization capability
  
  Serializes buffers' states stored on CPU.
  Gets buffers contents on GPU by mapping buffers to CPU's address space,
  then copy their data. Unmap buffers after finish. Since this feature is
  for tests only, it is only implemented for the Vulkan backend.
  
  Adds buffer serialization to serializeContext method so that capture
  replay regresssion testing now compares the states of buffers too.
