Implement Frontdrop/Backdrop Component According To Googles Guidelines

[JoeJHoward]

Is your feature request related to a problem? Please describe.
The Backdrop component doesn't follow the Material.io guidelines. I suppose we could implement something similar using a combination of built in MUI components, however it would take a lot of work. It would be good to have a native component that creates a frontdrop/backdrop UI.

Describe the solution you'd like
A frontdrop/backdrop UI component that follows the material.io guidelines

Describe alternatives you've considered
Could be accomplished using the MUI Modal component however would require significant amount customization.

Additional context
See the component guidelines Material.io Backdrop

At the moment we don't have plans to implement this component since it's still in design beta, but we'll keep an eye on it as it develops!
