Add configuration for grep-edit-mode

[hiecaq]

Brief summary of what the package does

grep-edit-mode is Emacs 31's built-in alternative to wgrep. Wgrep is more feature-complete, so I bind it as a fallback when wgrep is not available.

Checklist

Assume you're working on mpc mode:

• byte-compiles cleanly
• M-x checkdoc is happy. Don't manually write (provide 'evil-collection-mpc), M-x checkdoc can do it automatically for you
• define evil-collection-mpc-setup with defun
• define evil-collection-mpc-mode-maps with defconst
• All functions should start with evil-collection-mpc-

Is it possible to use both wgrep and grep-edit-mode in the same emacs session?

[hiecaq]

Technically yes, they implement a similar grep-mode <-> editable grep-mode behavior. But I believe the reason most people installed wgrep is for this editing grep result feature, which precedes grep-edit-mode by far (as it implements atomic updates, could be reverted, etc). The most benefit of grep-edit-mode is that it's built-in, so I consider it as a fallback as for now.

Lets split them then. I use wgrep most with dired, not grep.
