macOS packages do not ship debug symbol files *.dsym

And hence there's no debugging information at all. All the frames in lldb are assembly.

To test, write a simple gstreamer program, add a g_abort() anywhere, and run it under lldb.

This doesn't happen when building with gstreamer.git and using the development environment. Of course things break once you install gstreamer and try to use it from a prefix.

Here's what needs to be done:

1. Open a Meson pull request that adds support for installing *.dSYM files. You can look at how *.pdb files are handled for MSVC (Visual Studio) builds on Windows to check what to do. This should fix debugging symbols when installing from a gstreamer.git prefix
2. Figure out how to merge *.dSYM files. It's possible that the existing binary merging code will work as-is for these files once you tell it to look for those too. This should fix debugging symbols for a universal build cerbero shell.
3. Tell the cerbero filesprovider about the *.dSYM files so that these files are packaged correctly. You can again look at how *.pdb files are handled for MSVC on Windows. This should fix debugging symbols for a gstreamer framework installed from a package.
