Tell us about your environment

• ESLint version: v8.36.0
• eslint-plugin-vue version: v9.10.0
• Node version: v18.12.1

The problem you want to solve.

Add support for defineModel macro.

See https://github.com/vuejs/core/blob/main/CHANGELOG.md#330-alpha9-2023-04-08

Your take on the correct solution to problem.

Parser and some rules are affected. However, we have not yet listed the affected rules.
I think that, first, we need to list the rules affected by defineModel.
