Fix google#833: Switch to Qt 6.6.0 for macOS and Windows

With this commit macOS and Windows builds switch to Qt 6.6.0 [1], which
contains an important commit for Per-Monitor DPI support in Windows [2]
as discussed in google#831.

Note that '-no-feature-systemsemaphore' needs to be removed as otherwise
the build fails in macOS.
