The system menu is only support for macOS, so here just modify the macOS
platform special code.

The Windows, Linux used `ApplicationMenu`, I have already added
`checked` option to Zed's ContextMenu.

Then later when this PR merged, we can improve "View" menu to show check
state to panels (Project Panel, Outline Panel, ...).
