[Sema] Add and test new Subobject Attribute (#7258)
This PR adds and tests a new subobject attribute. It will be useful for checking if a given decl is a subobject decl. This functionality will be used in #7239 We need an attribute in order to determine whether to check its initializer for availability attributes or not. Fixes #7257
