App Store requires that our FFmpeg distribution includes dSYM files for
debugging symbols.
This patch removes stripping from the FFmpeg build, generates the
dSYM files and then manually strips the dylibs afterwards.
There was a minor conflict resolution due to .xcframework files
being stored in sudirectory 'framework/' rather than 'lib/' in
this branch.
