fix(material-experimental): better server-side rendering support for progress bar (#19036)

I got some changes in with material-components/material-components-web#5792 which allow us to properly render a progress bar during server-side rendering, instead of turning it into a noop. These changes remove all of the `isBrowser` checks.

I also removed the `isBrowser` check from the MDC checkbox, because the `offsetWidth` access is safe, even though the property might be undefined.
