Hello Contributors,

To help reduce the number of dependencies WebKit?s tools have, I would
like to replace our PHP tests (and resources used by tests) with Python 3
CGI scripts. I?ve already attempted to convert a few dozen PHP tests and
resources to demonstrate that this is both possible and that the resulting
Python is comparable to the existing PHP. Additionally, as advertised in
Big Sur, PHP is only included for compatibility with legacy software and is
not recommended.

There are still a few issues to resolve (namely, an issue with Python 3 on
some of our Windows machines), in the mean time, I want to determine if
other platforms have any issues with replacing our PHP tests with Python 3.

 BTW, after you finish the task, can we remove Python 2 supports from all
Python scripts? Or, should we keep Python 2&3 support until Mojave support
ends?
