[ffmpeg] fix linking with iconv feature (#13481) 
* [ffmpeg] fix linking with iconv feature

* [ffmpeg] use official iconv cmake target (broken for now, needs fix in libiconv, see #11776)

* [ffmpeg] fix typo in theora configuration

* [ffmpeg] switch to $<NOT:$<CONFIG:Debug>> for selecting release libraries

* [ffmpeg] use find_dependency(Iconv) on macos to better handle downstream REQUIRED

* Bump port version.

* [ffmpeg] remove iconv dependency on mac when it's not needed
