macOS: Allow non-cmd keyboard shortcuts to work on non-Latin layouts (#20336)

Updates #10972

Release Notes:

- Fixed builtin keybindings that don't require cmd on macOS, non-Latin,
ANSI layouts. For example you can now use ctrl-ա (equivalent to ctrl-a)
on an Armenian keyboard to get to the beginning of the line.
