fix(progress-bar): query state animation not working (#11459)

Currently the animation for a progress bar in the `query` state is disabled by default due to the `_noop-animation` producing the wrong selector. It looks like using the ampersand inside interpolation (e.g. in `@at-root ._mat-animation-noopable#{&}`) doesn't work as expected once we have more than one selector. What ends up happening is that SASS interpolates the first selector, but then leaves the other one as it is, which causes it to disable the animation.

Fixes #11453.
