Improve debugging performance

[timholy]

https://discourse.julialang.org/t/debugging-in-juno-extremely-slow/53801/4?u=tim.holy suggests a way that might be useful for many users. The suggestion later in the thread to put this under control of a checkbox seems to make sense.

I think we could probably add another checkbox here:

where we already have the "Compiled Mode" toggle. We could just add some toggles for base there.

OR, we could go really fancy, and show a complete tree view of every loaded module with a checkbox for every single one that allows a user to toggle them individually. Problem is that I don't think we could add that to the debug UI, it would have to live in the Julia (whatever the word is), so it would be a bit of a weird UI experience... So maybe we should not do that at the moment...

We can add views to the debug view container if I read this correctly.

Ah, that opens up an entire new world :)
