mkvtoolnix: updated to 87.0

Version 87.0 "Black as the Sky" 2024-09-07

New features and enhancements

* mkvmerge: chapters: added support for specifying MPLS files with
 `--chapters`, too, not just as regular source files. The documentation
 stated this was possible already, but that wasn't actually the
 case.
* MKVToolNix GUI: multiplexer: added a progress dialog that is shown during
 file identification.
* MKVToolNix GUI: jobs: the status bar now differentiates between numbers of
 warnings/errors that occurred in the current session and those that occurred
 before the current session.

Bug fixes

* mkvmerge: AAC parser: LOAS/LATM streams: if the first `AudioSpecificConfig`
 element is not found within the first LOAS/LATM frame, `mkvmerge` will no
 longer discard the frames before it but defer parsing them until after it
 has found the `AudioSpecificConfig` element.
* MKVToolNix GUI: job queue: fixed the GUI crashing when re-ordering the jobs
 in the job queue. This regression was introduced while fixing 3720.

Build system changes

* The bundled `fmt` library was updated to v10.2.1.
