QtEntryPoint: Fix linking Release against RelWithDebInfo with MSVC

To be able to link a Release user project against a RelWithDebInfo Qt we
set several IMPORTED_*_RELEASE properties in
the *AdditionalTargetInfo.cmake file of each Qt module.

The EntryPoint module however is a bit special as it is an
INTERFACE_LIBRARY linking publicly against a static
library (EntryPointimplementation). Its *AdditionalTargetInfo.cmake file
was almost empty, because qt_internal_export_additional_targets_file was
called before EntryPointImplementation was set up. Also,
qt_internal_add_module, which calls
qt_internal_export_additional_targets_file, does not know that we want
to export the EntryPointImplementation target.

We fix this by telling qt_internal_add_module(EntryPoint) to not
generate the *AdditionalTargetInfo.cmake file and call
qt_internal_export_additional_targets_file later to take the targets
EntryPoint and EntryPointImplementation into consideration.

qt_internal_add_module learned the option NO_ADDITIONAL_TARGET_INFO to
turn off the generation of *AdditionalTargetInfo.cmake files.

Pick-to: 6.0
