[Divider][material-next] Add Divider component

[Best-Sardar]

This issue is to track the work for adding the Divider component to @mui/material-next, moving forward the Material You effort (#29345)

Material You Divider specification: https://m3.material.io/components/divider/overview

Migration Guide steps

• Copy component files from material (v5) to material-next
• Remove deprecated components and componentsProps props
• Drop support for ThemeProvider in favor of CssVarsProvider
• Migrate component to Typescript
• Refactor component to use Base UI’s hook if it exists: There's no Base UI hook, pure presentation component
• Implement Material You design specs: PR #39179
• Add component playground to v5 docs: PR #39179
• Refactor styles to use component CSS Variables: WIP @rajvinder-kaur

@rajvinder-kaur sure, go ahead! Please try to follow Joy's Divider implementation. It's not necessary to have all the variables Joy has.
