Refactor .zshrc

- Split login stuff into .profile
- Symlink .profile to .zprofile since zsh only loads the latter
- Drop QPA_PLATFORMTHEME and see what breaks
- Make bat my pager where I have it, most where I don't
- Drop the OS-detection stuff for ls, use exa if I have it
- Drop a couple old aliases
