[QGIS-Developer] MacOS Qt6 builds / Notarization

[Matthias Kuhn]

Dear all,

Over the last few months I've made good progress on the mac build front.
Since the beginning of the year, a pull request has been open that builds
QGIS against recent, updated dependencies and Qt6 and creates a dmg
installer for download.
These packages provide universal binaries that work natively on Intel x64
and ARM machines.

Overall, the feedback of testers has been encouraging and many things could
already be ironed out.

Since last week it is now also possible to download notarized versions of
these builds. The scripts are in https://github.com/opengisch/qgis-notarize/
and in the actions on this repository, the notarized packages can be
downloaded and we also have encouraging feedback there.
Eventually I would like to only notarize releases (and not pull requests)
and use an OSGEO certificate (not the current OPENGIS.ch one) and produce
the packages on a repository under the qgis organization. I'll handle that
in the upcoming weeks.

Since this is a complete refactoring and cleanup of the mac build chain, it
would break the current Qt5 builds and was therefore not merged to not
break releases on the QGIS 3 series.

With the last minor release QGIS 3 approaching, I would like to proceed
with merging this right after 3.44 has been branched off. The pull request
is rather large so it's good if this has a long cooldown period before it's
released with QGIS 4 later this year. Whoever feels comfortable reviewing
cmake code changes, please do so before Friday next week, June 20.

Thanks a lot and best wishes
Matthias
