We currently don't have any machinery for qmake or CMake to map
translations declared via TRANSLATIONS += or qt_add_translations
to the Info.plist CFBundleLocalizations key.
This results in macOS and iOS falling back to the development region,
CFBundleDevelopmentRegion, as the only supported localization of the
app, which is in most cases set to 'en'.
Unfortunately this doesn't work well with the behavior of iOS 11+
and macOS 10.13+ where the OS will set the locale of the app to
the best match between the app's supported localizations and the
user's preferred language.

Since we only support a single localization, the development region,
the locale always ends up as 'en_<REGION>', which after QTBUG-104930
is also reflected in the QLocale's uiLanguages(), resulting in the
QTranslator machinery always picking English translation for the app.
As long as we don't explicitly declare CFBundleLocalizations we need
to opt out of the system's behavior of finding the best match between
the app's declared localizations and the user's preferences, which we
can do via the CFBundleAllowMixedLocalizations key.

The key only applies to macOS bundles. Also, qmake doesn't have it.

To support per-target iOS launch screens we need a way to specify
custom Info.plist entries without using cache variables, which we were
forced to use due to the implicit configure_file done for
MACOSX_BUNDLE_INFO_PLIST.
We now introduce an extra configure_file call done in a finalizer,
before we hand off the Info.plist file to MACOSX_BUNDLE_INFO_PLIST.
This extra configure_file call allows us to insert / substitute
additional Info.plist entries that CMake does not allow setting.
If a custom Info.plist file is provided, the finalizer will simply
skip the logic for creating a new one.
