[Lldb-commits] [lldb] [NFCI][lldb][test] Add missing <functional> includes (PR #165772)

[Raul Tambre via lldb-commits]

https://github.com/tambry created https://github.com/llvm/llvm-project/pull/165772

`std::ref()` is provided in `<functional>` and with recent libc++ changes it no longer seems to be included transitively. Fix by including explicitly.
