Support macOS Configuration Profiles as a policy backend

[joaomoreno]

• Generate .plist files from our configuration registrations (Generate macOS configuration profiles #241773)
• Implement a Configuration Profiles policy source (@vscode/policy-watcher 1.2.0 #243132, Implement MacOS  vscode-policy-watcher#44)

If the only purpose of this feature request is to use it as a placeholder when closing other duplicate requests, then . . .

Can we get an update re: whether this is ever going to be moved off the backlog? Especially now that:

• Enterprise Extension management has GAed
• Copilot Free is a thing

It is increasingly critical that enterprises be given management tooling for VSCode which isn't Windows-only.

Yes, I recognize that it's a free offering. It's also the world's most popular code editor/IDE.

@rossgrady Moving it out now. 👍
