Vim compat: Support closing search bar with <ctrl-c>

[zenazn]

Describe the bug / provide steps to reproduce it

In vim, typing /foo will start a search for foo. While in the search context (i.e., the cursor is in the bottom search bar, like /foo| with | being the cursor; in other words before pressing enter), typing control-c (<C-c>) will cancel the search, much like pressing escape (<Esc>).

In Zed this behavior does not work. Below is a screenshot of the state of the editor after typing /foo. <Esc> behaves as expected and cancels the search (returning focus to the editor), but <C-c> does not cancel the search. Instead, it does nothing.

This actually confused me when I started using Zed as well, so definitely see where you're coming from.

However, when it comes to UI and stuff like that our goal isn't always to have 1:1 behavior match with vim, so I'm going to put this in the Features/Enhancements category and we can think about adding this / whether it will cause conflicts or other problems.
