[Andreas Rheinhardt]

ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt at outlook.com> | Sun Mar  2 15:27:48 2025 +0100| [57f184221df261e041fcacc29fc1d4da196436ef] | committer: Andreas Rheinhardt

avutil/attributes_internal: Add EXTERN macro for extern+hidden

This is inspired by the equivalent dav1d attribute introduced
by Henrik Gramner in e4c4af02f3de5e6cea6f81272a2981c0fa7bae28.
Also already use it to beautify declarations.
