Sonoma API improvements

[NattyNarwhal]

• Use modern NSTableView customization API
• Change NSButton styles
• Anchor NSPopovers to toolbar items
• Review new NSMenu selection modes
• Review clipToBounds behaviours
• Symbol bounce
• #Preview macro
• Use inspector split view
  • May be annoying with how we construct the split view and still using nibs for toolbar instead of delegate
• TipKit?
  • Maybe require more SwiftUI
• Composite Core Data types
• Staged migration API, deferred migrations

I think the way to handle the inspector separation with traditional nibs is making an item in the palette for NSToolbarInspectorTrackingSeparatorItemIdentifier, like we have for NSToolbarSidebarTrackingSeparatorItemIdentifier

[NattyNarwhal]

I'm going to have to be adjust the main window nib too, default toolbar button metrics changed to be a bit longer...

[NattyNarwhal]

I think the toolbar button metrics change if you customize the toolbar.

The font size on the time fields also looks wrong.

This works, but you can't set the edge it comes from, which means it's a bit awkward as it'll appear above the toolbar item.
