This is a reland of commit 50a0f5cfa8
Original change's description:
> [GTK] Support Emacs bindings on GTK4
>
> This change replaces the old vector‐based API
> GetTextEditCommandsForEvent with a function that returns a single
> ui::TextEditCommand. INVALID_COMMAND is returned when no valid command
> applies. The command mapping no longer relies on heap-allocated data
> (vector and string), so can now be a compile time constant.
>
> The old code used a complex signal handling approach that simulated a
> keypress in a fake window and widget to observe the resulting text edit
> command. However, the only "key theme" GTK ever supported was emacs
> bindings before key themes were removed in GTK4. This CL simplifies the
> approach by directly mapping key events to edit commands. It also
> enables emacs bindings on GTK4 and (eventually, when this code is moved
> out of //ui/gtk since it no longer has any GTK dependencies) QT.
