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

[via cfe-commits]

https://github.com/smanna12 created https://github.com/llvm/llvm-project/pull/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.
