terminal: Add fzf file insertion and zoxide cd key binds

The following is added to all three shells bash, zsh, nushell:

Pressing c-t at any time lets you insert a file/dir at the current
cursor location using fzf. Same for 'T' in vicmd mode.

Pressing alt-c at any time lets you jump to that directory using zoxide,
with the zle editor content intact. Same for 'C' in vicmd mode.

Zsh implementation from: https://github.com/ajeetdsouza/zoxide/issues/357
Bash implementation: https://github.com/ajeetdsouza/zoxide/issues/516

Nushell implementation taken from: https://github.com/junegunn/fzf/issues/4122

TODO: Nushell fzf mapping has one problem in that it does not quote the
selected file in any way. So any file with e.g. a space in it will have
to be manually fixed afterwards.
