fix: avoid layout jumping on elements with ripples in RTL (#10026)

A while ago we added a `backface-visibility` to some components that have scrollable content in order to avoid repaints while scrolling (see #7889, #7721, #7719, #6890, #2156) which worked at the time, however in the more recent versions of Chrome it causes the content in RTL mode to shift whenever a child has a transform that is being animated (in our case it's usually ripples). These changes revert the `backface-visibility` in order to avoid the jumping, until we can find a better solution.

Relates to #10023.
