tools: Use raw strings for regexps in python scripts (fixes #3677)
Starting with Python 3.12, use of invalid escape sequences in strings is reported as a SyntaxWarning and will become a SyntaxError at a later point. Regular expressions use the backslash character a lot, which result in warnings of this kind. Python docs recommend to generally use raw strings for this purpose.
