qt5-qtwebengine @5.15.2: does not yet build on arm64

[kencu (Ken)]

<​https://bugreports.qt.io/browse/QTBUG-85537>

I thought I would put this here before anyone else does.

Has duplicate #63434.

The referenced upstream issue has been closed. Perhaps that means we can now fix this problem in MacPorts.

[chrstphrchvz (Christopher Chavez)]

Unlike the rest of Qt 5.15, QtWebEngine 5.15.x releases continue to publicly tagged in its git repository (although not as tarballs to the current master_sites). I would suggest switching qt5-qtwebengine to these newer releases (possibly using tarballs generated by the ​qtwebengine and ​qtwebengine-chromium mirror repositories on GitHub), as it may not be trivial to backport the Chromium fixes both for security issues and for supporting macOS on ARM.

I have only tested the patch phase. I leave it to others with full Xcode and/or Apple Silicon Macs to verify the update actually works.

Thanks to a volunteer tester, some progress has been made. Currently it is stuck on an error during linking, which I have located essentially no discussion of elsewhere:

Is something missing from system libc++? (Is that even a likely scenario?)

Edit: this is the error #63725 described
