cmTarget: Require a compatible INTERFACE_AUTOUIC_OPTIONS from dependencies.

Revert the origin-tracking infrastructure from commit 98093c45 (QtAutoUic:
Add INTERFACE_AUTOUIC_OPTIONS target property., 2013-11-20). Use the
compatibility-tracking for compatible strings instead.

If two different dependencies require different AUTOUIC_OPTIONS,
cmake will now appropriately issue an error.
