The def_property family blindly ignore the keep_alive and call_guard arguments passed to them making them confusing to use. This adds a static_assert if either is passed to make it clear it doesn't work. I would prefer this to be a compiler warning but I can't find a way to do that. Is that even possible?

(random timing, I'm cleaning up my email backlog) Looks good, thanks! — 'll get back here a few days after #5542 is merged, but before the v3.0.0 release. |

I think the android runner is broken. This is also an issue in #5896 |

Description
The def_property family blindly ignore the keep_alive and call_guard arguments passed to them making them confusing to use.

This does not fix - #4236 or #5046 but makes it clear that they don't work.
