[docs] Restore utility component docs from MUI Base to Material UI

[mapache-salvaje]

Since the new @mui/base-ui has diverged significantly from the (now legacy) MUI Base package, utility components from MUI Base that also live within Material UI will remain in the latter package for now, with no immediate plans to deprecate. As such, this PR restores the docs for the components in the Material UI docs space and removes the deprecated chips from the nav bar.

We'll need to move the demos too and make sure in them we import the components from @mui/material. The content looks good to me 👌

@mnajdova Looks like they're all still in their respective directories—for example: https://github.com/mui/material-ui/tree/master/docs/data/material/components/click-away-listener

It appears they were never deleted when we removed the content from these pages. (I did miss a typo on one demo that was causing the build to fail, but it should be good now.)

I think this makes sense to stop pushing users into a deprecated package.
