Step up python stack until we find our globals, or run out of stack

Browse Source 
* In python globals aren't really global, they're just module-level
  variables. So to find our _renderdoc_internal we have to potentailly
  walk the stack if we're inside another module until we get to the
  globals dict we set up.
