Fix macos bigsur cvbuffer crash (#13392)

* Fix macOS Big Sur crash with CVBufferCopyAttachments

Add FFmpeg patch to use weak_import for CVBufferCopyAttachments API
to prevent dyld crash on macOS Big Sur (11.x).

The CVBufferCopyAttachments function is only available on macOS 12+.
Even though FFmpeg has a runtime check with __builtin_available, the
symbol is still resolved at load time, causing immediate crash on older
macOS versions.

With weak_import attribute, the function pointer will be NULL on
macOS < 12, allowing the code to safely fall back to the deprecated
CVBufferGetAttachments API.

Fixes: #13377
