MacOS fix compilation errors and correct app icon and title (#202)

- Adds ICONV_LIBRARY to CMakeList to fix ffmpeg compilation error
- Replaces the app icon from yuzu.icns to eden.icns
- Changes app title and name from yuzu to eden
- Updates MoltenVK to 1.3.0

Note: The wiki also needs an update, after merge to master I'll edit the wiki. The wiki says to installs Qt5 but eden uses Qt6.
