Add widget for nu exe (debug/release, and main vs other branch) (#634)

Browse source 
Full line prompt looks like:
```
---<exeStatus>---------- <workingDirectory> ------ <gitRepoStatus> --- <dirs>
>
```
Where `<exeStatus>` shows `<exe-path> <exe-branch>`, 
but is empty if:
* nu exe running from a "bin" folder (based on `$nu.current-exe` path)
* nu exe built from a "main" branch (otherwise shows `(version | get
branch)`)
