Bug 1855763 - Disable -moz-transform and enable zoom on Nightly. r=zcorpan

Disable zoom on a couple tests that otherwise fail. They're known
issues:

 * offsetWidth/Height not being unzoomed (button-min-width).
 * getComputedStyle not being unzoomed (font-size-interpolation-003.html)
 * ResizeObserver box not being unzoomed (w3c/csswg-drafts#9398).
