valgrind-monitor.py regular expressions should use raw strings
    
    With python 3.12 gdb will produce the following SyntaxWarning when
    loading valgrind-monitor-def.py:
    
      /usr/share/gdb/auto-load/valgrind-monitor-def.py:214:
      SyntaxWarning: invalid escape sequence '\['
        if re.fullmatch("^0x[0123456789ABCDEFabcdef]+\[[^\[\]]+\]$", arg_str):
    
    In a future python version this will become an SyntaxError.
    
    Use a raw strings for the regular expression.
