python: Add the ability to check if a debug flag has been enabled

Browse Source 
There is currently no Python API to check if a debug flag is
enabled. Add a new status property that can be read or set to control
the status of a flag. The stat of a flag can also be queried by
converting it to a bool.

For example:

  m5.debug.flags["XBar"].status = True

  if m5.debug.flags["XBar"]:
      print("XBar debugging is on")
