Add a local breakpoint mode

[aidan-hall]

A trivial change that can be perfectly backwards compatible:

1. Rename dape-breakpoint-global-mode to dape-breakpoint-mode and make it a non-global mode (possibly with a lighter).
2. Add a define-globalized-minor-mode for dape-breakpoint-global-mode based on dape-breakpoint-mode.

Use case: I only want the dape breakpoint bindings active in prog-mode-derived buffers. The current global mode overrides fringe click bindings in all buffers, even ones dape will never step into, such as the Magit status buffer.

Hello, and thank you for your suggestion!

I think it makes perfect sense.

Previously, dape-breakpoint-toggle would show a warning if the current mode wasn't derived from prog-mode. It seems obvious now that the better solution is simply to skip buffers that aren’t derived from prog-mode altogether (as in your use case). This can easily be done by using that check as a predicate in the turn-on function that enables the globalized mode.

Now you can enable dape-breakpoint-global-mode without it interfering with Magit's fringe bindings, since it won't be enabled there.

I hadn't even thought of that, sounds great!
