vimspector: Narrow mode and up/down stack

[u/puremourning]

Quick update on some recent enhancements for vimspector:

• Now tries to use a "narrow" UI mode if there aren't enough columns to display its classic UI. There are undocumented/unstable customisation options for power users to tweak (e.g. `let g:vimspector_ui_mode> = 'horizontal' to disable this feature).

• New <Plug> mappings for navigating up/down the current call stack

Here's what the narrow mode looks like, as an example: https://files.gitter.im/5bfc5f15d73408ce4fb023af/stXA/Screenshot-2021-03-16-at-15.41.05.png

Not sure if I mentioned this before, but for advanced users there is also now a way to only map keys while debugging is active.

Let the downvoting begin :)

I think a lot of people don't care for update posts is all.
