Fix multiple-rules-for-target error
The old logic for BUILD_SHARED_LIBS and BUILD_SHARED_AND_STATIC_LIBS would produce two targets with the same name and different build rules. The Makefile generator tolerated this, but the Ninja generator raised an error. Fix the logic so that only one shared and one static target gets built, and make the pugixml target an ALIAS of the one dictated by BUILD_SHARED_LIBS.
