Fix `shape` and `collapsedShape` isn't applied to `ExpansionTile`'s splash ink (#141777) 

This updates the previous attempt https://github.com/flutter/flutter/pull/135855 and removes the complications when testing M3 ink sparkle effect. 
Thanks to this [PR](https://github.com/flutter/flutter/pull/138757) by @Piinks 

fixes [ExpansionTile InkSplash doesn't respect Shape's borderRadius](https://github.com/flutter/flutter/issues/125779)
fixes [`ExpansionTile.backgroundColor` &  `ExpansionTile.collapsedBackgroundColor` removes splash effect](https://github.com/flutter/flutter/issues/107113)
