Support mac/linux/windows subkeys in keybindings.json the same as extensions.contributes.keybindings...

Issue Type: Feature Request

For users running on multiple machines/platforms, it is common to sync the vs settings. Without support for the default 'key' and override-platform-specific 'windows/mac/linux' subkeys, there's no good way to share keybindings.json.

Keeping multiple copies is a pain to keep in sync; and with the commonality of 'cmd' on Mac in particular, it's hard to have a true common config that works across platforms.

I may be underestimating the work, but it looks like the most tedious/difficult part would be extending the localization of the schema in keybindingservice.ts. :)

There does not seem to be a write model that would need to preserve the original values.
(writeKeybindingItem looked like it might be it, but it's generating very specific formatting for the Default Keybindings window. I guess it could be used by something more general and OS specific bindings would be lost?)

The attached PR #45995 has an implementation; and tests. I've attempted to make sure there are no downstream effects; but not being fluent in non-extension code, I won't claim it's ship ready.
