Adds @(no_instrumentation) to spall buffer and SCOPED operations

Currently without this scoped event names are not displaying correctly when auto-tracing is enabled.
The buffer_destroy event, obviously, fails to be completed (as theres no buffer to write the end event to, and context_destroy should happen after all the buffers are destroyed so there's, again, no buffers to write to.
