Feature Request: Provide hook for text-edits for VC control

[pfurnanz]

Some eglot actions (for example eglot-rename) can make project wide changes. In some version control systems, files are read-only until explicitly marked for edit by the users. It would be nice to have an eglot-apply-text-edits-hook that is run in the current buffer before applying changes so that users may arrange to mark the file for open.
