Create quiche_callbacks.h

quiche_callbacks.h introduces the following type aliases:
  - quiche::UnretainedCallback (alias for absl::FunctionRef)
  - quiche::SingleUseCallback (alias for absl::AnyInvocable with && qualifier)
  - quiche::MultiUseCallback (alias for absl::AnyInvocable with const qualifier)

Those are meant to replace existing usage of std::function in QUICHE.
