  Bug 1799982 - Remove uses of inline flags from XPIDL regexps. r=xpcom-reviewers,kmag a=RyanVM
  
  Apparently the use of these is being turned into an error in Python 3.11.
  Fortunately, our uses appears to be rather trivial.
  
  For t_multilinecomment and t_LCDATA, I dropped the (?s) flag and just
  replaced the one use of . with (\n|.). (?s) means DOTALL, which means
  that dot includes any character, including a newline. Otherwise it means
  dot includes any character except a newline.
  
  I took the new t_singlelinecomment from IPDL's parser.py, so I assume
  it is reasonable enough. t_multilinecomment is also now the same as
  in IPDL.
