Subject: [PATCH] [Switch] Fix morphing time of switch thumbs

The switch thumb position animation time is hard-coded by SwitchCompat and we have no way to override it. Therefore, the morphing time has to follow the position animation time, instead of the design spec.

Resolves https://github.com/material-components/material-components-android/issues/3340
