D3D12: Optionally prevent StreamBuffer from executing command list

Browse Source 
This applies to callers that do not have full knowledge of the command
list state, and thus, cannot restore it should allocations cause command
list execution. Instead we reallocate a new buffer. Should not happen
often enough for this to be a concern, as it's mainly for the utility
classes.
