Remap ⌘ (Command) to Ctrl when VSCodeVim is active

Is your feature request related to a problem? Please describe.
I'm a Vim user who developed muscle-memory on PC-style keyboards. When I switched to Apple-style keyboards, I used the iTerm2 configuration option to remap Left-⌘ to Left-Ctrl. Many critical Vim features depend on Ctrl- chords, but switching to VSCode with VSCodeVim, I found no equivalent configuration option, resulting in a situation where I am entering many erroneous ⌘- chords when I intend to enter Ctrl- chords.

Describe the solution you'd like
The ideal solution for me would be a configuration option where VSCodeVim will remap Left-⌘ to Left-Ctrl for any context in which it is actively interpreting my keystrokes in a Vim way.

It would be ideal to remap the Left-⌘ and/or Right-⌘ independently, not both, since it is still important to have a ⌘ key available in whatever context. The implementation in iTerm2 works great, so it might be a useful reference.

Describe alternatives you've considered
I have looked at VSCode built-in options and not found any such option. I have considered 3rd-party applications, but installing these is not possible on my employer-issued computer.

Additional context

Start by reviewing how VSCodeVim interprets keystrokes in Vim contexts and how VS Code exposes Command and Ctrl keybindings on macOS. Use the iTerm2 behavior and linked StackOverflow question as reference, then define how left and right Command remapping should be configured independently and when the remapping applies.
