fix(material/tabs): remove visibility style when hydrating (#29220)

Before this commit, when using pre-rendering, the styling animation would only remove the `transform` style when hydrating the component. This commit fixes this by including `visibility` as styles to remove when playing the animations.

(cherry picked from commit e95d88c)
