python3Packages.qemu: fix shadowed qemu; improve expression

- fix all shadowed references of qemu in python-packages.nix
- migrate to pyproject = true
- add a check to ensure that the version attribute is up to date
- implement check phase testing all executables
- enable tui and fuse support by default for the application only
- if fuse/tui disabled, ensure that corresponding executables are not exported
