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.

 http://thread.gmane.org/gmane.comp.kde.devel.frameworks/7930/focus=7992

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

+INTERFACE_AUTOUIC_OPTIONS
+-------------------------
+
+List of interface options to pass to uic.
+
+Targets may populate this property to publish the options
+required to use when invoking ``uic``.  Consuming targets can add entries to their
+own :prop_tgt:`AUTOUIC_OPTIONS` property such as
+``$<TARGET_PROPERTY:foo,INTERFACE_AUTOUIC_OPTIONS>`` to use the uic options
+specified in the interface of ``foo``. This is done automatically by
+the :command:`target_link_libraries` command.
+
+This property supports generator expressions.  See the
+:manual:`cmake-generator-expressions(7)` manual for available expressions.
