[Discover] [Dashboard] [Embeddable] Hide full screen button for saved search embeddables (#156774)

## Summary

This PR hides the full screen button for saved search embeddables since
the full screen mode can result in display issues when parent elements
use CSS transforms.

Originally I was trying to figure out how to only hide the full screen
button when used in a dashboard, but it turns out that saved searches
embedded in Canvas have the same issue, so I think it makes sense to
just disable the full screen button entirely for saved search
embeddables until we have a reason to do otherwise:

Resolves #151499.
