Genex: Add {UPPER,LOWER}_CASE and MAKE_C_IDENTIFIER.
QtAutoUic: Handle new -include command line parameter.
QtAutoUic: Add INTERFACE_AUTOUIC_OPTIONS target property.

Transitively consume the property from linked dependents.

Implement configuration-specific support by following the pattern
set out for compile definitions and includes in cmQtAutoGenerators.

Implement support for origin-tracking with CMAKE_DEBUG_TARGET_PROPERTIES.

This is motivated by the needs of KDE, which provides a separate
translation system based on gettext instead of the Qt linguist
translation system. The Qt uic tool provides command line options
for configuring the method used to translate text, and to add an
include directive to the generated file to provide the method.

Implement the interface to provide the uic options as a usage-requirement
on the KI18n target, as designed for KDE.
