Migrate from setuptools to meson-python

[oriori1703]

While working on publishing wheels I realised the build could be modernised and simplified by using meson-python.

This allows us to use more modern packaging standards (like pyproject.toml) and fits well with the existing meson build system.

TODO:

• Fix building with frida-python (unless we remove it as suggested in a previous comment) Removed the dependency for now
• Fix version detection. For now I just hardcoded it in the meson.build
• Fix license not being recognised by the build system

Nice! The only issue I can see with this approach is that we have a Meson wrapper that takes care of downloading prebuilt tools + libraries. Not sure we want to lose this.

As far as I understand, all of the libraries and tools that are downloaded are not really need when developing frida-tools.
Also, if you still think it is useful to have those tools you can just direct people to the frida/frida repo which functions the same way (download all of the related projects, and all the tools needed to build them).

I have fixed all other issues, so if you agree with removing frida-python as a dependency, everything should be ready to merge 😄

BTW, The sdist won't build on python 3.7/3.8 unless frida/releng#14 is applied.
The wheels will work fine though :)

Thanks! (And apologies for the delay.)
