This adds a mechanism for running generic operations at specific points of the frame execution. This can be used by any part of the code an not just Lua since it simply executes std::functions. It also adds an "execution context" concept that specifies in which situation an operation should be executed. This is then used by the Lua Coroutines code for resuming coroutines at specific points instead of always when the awaited promise resolves.
