qt6: updated to 6.8.0

6.8.0

For this release we have focused on improving and stabilizing existing
functionality. With over 500 bug fixes and performance improvements since Qt
6.7, your existing code will run better without changing a single line. On
macOS, Qt Quick applications now integrate with the native menu bar, and for a
native Windows 11 look they can use the new Fluent style. Resizing Quick
windows is snappier on macOS with Qt 6.8, and on Windows the application
start-up time has been improved by changing the default font database to
DirectWrite.

Several modules that were under technology preview have been completed: Qt
Graphs, Qt HttpServer, and Qt GRPC are promoted to be fully supported from this
release on. Thanks to the feedback from our users we were able to finish those
modules with substantial improvements since their initial introduction as
technology previews.
