[Rating] Fix a few issues

[oliviertassinari]

• Fix hover logic. This is a recent regression ([Rating] Improve rendering of arbitrary precision  #17013), I have added a test for it.
• Display inline instead of block. I have used the component in https://themes.material-ui.com, I quickly realized that we could have a better default. This change is breaking. I have looked at a couple of the generic rating components, the benchmark confirms that display inline is likely a better default.
• Fix warning in the demos. This is a recent regression.
• Remove the need for ownerWindow(). As it turns out, we can do the computation with the viewport as the origin (getBoundingClientRect + clientX). This should help with the bundle size.
