Test OBJECT library failure cases
Add "RunCMake.ObjectLibrary" test to verify that unsupported use cases are rejected with errors: * An OBJECT library may not reference another object library * An OBJECT library may not be referenced in target_link_libraries * An OBJECT library may not contain non-compiling sources * An OBJECT library may not have pre/post build/link commands * An OBJECT library may not be installed, exported, or imported Also verify that invalid $<TARGET_OBJECTS:...> expressions are diagnosed.
