[Clang] Prevent Copying of LateParsedClass Instances (#109428)

Class clang::Parser::LateParsedClass owns resources that are freed in
its destructor but has no user-written assignment operator.
This commit explicitly deletes the copy constructor and copy assignment
operator for the LateParsedClass.
