  Tests: Add support for --renderdoc
  
  This change adds support for a new flag namely `--renderdoc` to end2end
  and deqp tests.  With this flag, each test automatically starts and ends
  a frame capture in renderdoc, working around an issue where renderdoc
  refuses to capture a test frame that doesn't start or end with a swap.
  
  With end2end tests, the capture starts before test set up, and ends
  after test tear down.  With deqp tests, it starts before init, ends and
  restarts after each test iteration and ends after deinit.
