bug#65519: 30.0.50; [FR Eglot] keymaps for useful functions

[Gerd Möllmann]

There are some useful eglot functions that can currently only invoked
with M-x, by default.  I'm currently defining a keymap

(define-keymap :prefix 'my-eglot-bindings
  "a" 'eglot-code-actions
  "f" 'eglot-format
  "h" 'eglot-inlay-hints-mode
  "r" 'eglot-rename)

that I bind to a a prefix key in c-mode-common-hook.

Feature request: Could eglot-mode do something like that?
