bug(MENU): Types of property 'hasBackdrop' are incompatible

### Is this a regression?

- [X] Yes, this behavior used to work in the previous version

### The previous version in which this bug was not present was

Definitely worked in 12.2.9, didn't check with later versions

### Description

On version 13.1.0 with `exactOptionalPropertyTypes` flag,
when trying to use the Menu component, following error shows up in Terminal:

### Reproduction

StackBlitz Example project doesn't build on latest version, so I couldn't reproduce it for you. You can see it working on v12: https://stackblitz.com/edit/components-issue-fau7sh?file=src%2Fapp%2Fexample-component.html.

To check locally, create a new Angular 13 project, install the material library and enable the `exactOptionalPropertyTypes` flag in `tsconfig.json`

### Expected Behavior

Code compiles and Menu works.

### Actual Behavior

Code doesn't compile, Menu doesn't work.

### Environment

- Angular: 13.1.0
- CDK/Material: 13.1.0
- Browser(s): Chrome 96
- Operating System: Windows 11

If you guys have any questions, let me know

まず、issue に記載されている Angular 13 プロジェクトを作成し、tsconfig.json で exactOptionalPropertyTypes を有効にして、Menu コンポーネントを使用します。バージョン 12.2.9 と型エラーを比較し、関連する Menu の型定義を調べます。プロジェクトがコンパイルされ、flag を有効にした状態で Menu が動作すれば完了です。
