Steps to reproduce 🕹

Link to live example: https://codesandbox.io/s/menu-paper-slot-replaces-default-cwtyk7?file=/src/App.tsx

Steps:

1. Use the Menu component
2. Provide slots and/or slotProps prop

Current behavior 😯

The slots and/or slotProps provided are passed to the Popover component, and override the ones provided in the Menu component even when a slot is not being passed.

In the example, only the root slot is provided but the paper slot is overridden, so MenuPaper is not used.

Expected behavior 🤔

The slots and slotProps should be merged so they're not overridden if not intended.

Context 🔦

The slots and slotProps are new Popover props introduced in https://github.com/mui/material-ui/pull/37390. the Popover props are also available from the Menu component. As they're used in the Menu component, they should be fully supported and merged with the external ones.
