Do not store flags in qmake.cache with WEBENGINE_CONFIG.
Use directly qtConfig values insted. This makes configuration
more consistent, simplifies handling and avoids passing
values from qtConfig to WEBENIGNE_CONFIG, which then
were passed to gn.

Previously when Airplay was activated and a new QWebEngineView instance
was created, a black area would be rendered inside the view.
This happened because of incompatible OpenGL contexts. The global Qt
OpenGL context could not share its textures with the newly created
"after-airplay" context, due to the contexts being used by different
GPUs (only possible on a MacBook Pro).

The fix is to add the NSSupportsAutomaticGraphicsSwitching option into
the application plist file, which informs macOS that the application
supports usage of dual GPUs, and thus allows sharing of contexts
across GPUs.
