Damien Elmes 7ba32cce6d Migrate build system to uv
Closes #3787, and is a step towards #3081 and #4022

This change breaks our PyOxidizer bundling process. While we probably
could update it to work with the new venvs & lockfile, my intention
is to use this as a base to try out a uv-based packager/installer.

Still to do:
- move mpv distribution to a wheel
- build the new uv-based installer.

Some notes about the changes:

- Use uv for python download + venv installation
- Drop python/requirements* in favour of pyproject files / uv.lock
- Bumped to latest Python 3.9 version. The move to 3.13 should be
a fairly trivial change when we're ready.
- Dropped the old write_wheel.py in favour of uv/hatchling. This has
the unfortunate side-effect of dropping leading zeros in our wheels,
which we could try hack around in the future.
- Switch to Qt 6.7 for the dev repo, as it's the first PyQt version
with a Linux/ARM WebEngine wheel.
- Unified our macOS deployment target with minimum required for ARM.
- Dropped unused fluent python files
- Dropped unused python license generation
- Dropped helpers to run under Qt 5, as our wheels were already
requiring Qt 6 to install.
