CMake: Post-WX cleanup

- Remove unused build options

 - Disable setcap by default
    Applications should not need to call sudo as part of the build process.

 - Rename XDG_STD to USE_LEGACY_USER_DIRECTORY
    By default, we use ~/.config/PCSX2 now.

 - Default Wayland support to on
    I don't think there's any systems worth supporting that don't have it.

 - Rework "install" logic
    Linux no longer installs to GIT_ROOT/bin, it builds direct to BUILD/bin.
    Saves a file copy, and running make install before running your developer
    build was always silly.

 - Don't require install target to build appimage
    AppImage creator now just adds the entire bin directory as-is.
    Everything needed is in there.
