Use pyproject.toml to enable building and installing from source

[bkmgit]

Operating system: Linux Mint Debian Edition 6
wxPython version & source: wxPython 4.2.2 Pypi
Python version & source: python 3.11 system

Description of the problem:

Get the following warning when building:

DEPRECATION: wxPython is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559

The current build uses setup.py which is deprecated. Would switching to using a pyproject.toml configuration be something that would be supported? There is an old pull request at here, but am happy to update this or make a new one if it would be examined.

Yes, it's something that's desired. I've tried to work on it a little bit myself, but haven't gotten very far. I attempted to turn build.py into a PEP-517 build system, but ran into some conflicts with the build PyPI module...

Contributions are welcome.

I've passed 3 days over the last two weekends on this. I didn't know you were open to changing up much of build.py. I was tuning up to make sure that I had only the minimal changes that I would be full certain that it wouldn't break with other invocations/ways of using it that I wasn't aware of.
I'm only one misplaced file away from having a first step ready. The wx.svg is misplaced in two folders in the build package.
Adding a pyproject.toml forces you to opt-in to a different behavior and different defaults that projects were supposed to be using already, so it is a kind of debt to fight against.

Well, my attempts were also to change it very minimally. But looking forward to your change proposal, thanks a lot for working on that.
