Backport PR #10797: Let keyboard interrupt stop custom dispatch of completer. See 10733, interruption during custom completer can crash the kernel. Technically we should likely even protect normal completion (like jedi taking a while), but let's get something that fix an actual bug. This can lead to some inconsistencies in the frontend, as you interrupt the kernel in Command mode, and interrupting the current custom completer will lead to normal completion being (still) returned and the completer poping up in command mode. It's not optimal but at least we do not loose user state. Alternative to 10792, I like to have a better, more general fix, but that will actually fix a case with crash where we do have bug reports, and can be backported to 5.x
