Modify key info generation for new iOS key code. (#83439)

Browse Source 
The (new, not yet used) code gen for iOS was setting up a std::map from key codes to logical and physical key codes, but it was using uint32_t, which isn't big enough to hold the Flutter key codes.

Also, iOS needs to be able to filter out function keys, so I added a function key set.
