Use case

The Material 3 specification has a section about Dividers in DropdownMenus.

See item 6 in the spec: https://m3.material.io/components/menus/specs

However, the DropdownMenu API currently only allows a list of DropdownMenuEntryitems, which each require a value and a label. This prevents using a Divider, as the divider has no real value.

Proposal

Implement a new DropdownMenuEntry subclass, DropdownMenuDivider, which has no value or label and just inserts a Divider per the Material 3 example (using the M3 divider specs). No selection change should happen when a Divider is tapped.
