Adds OverscrollEffect#withoutDrawing and OverscrollEffect#withoutEventHandling

Expand for full commit details

Adds OverscrollEffect#withoutDrawing and OverscrollEffect#withoutEventHandling 
 
These APIs allow overscroll to have events dispatched to it by one component, and rendered in a separate component.

Fixes: b/229537244 
Test: OverscrollTest 
Relnote: "Adds OverscrollEffect#withoutDrawing and OverscrollEffect#withoutEventHandling APIs - these APIs create a wrapped instance of the provided overscroll effect that doesn't draw / handle events respectively, which allows for rendering  overscroll in a separate component from the component that is dispatching events. For example, disabling drawing the overscroll inside a lazy list, and then drawing the overscroll separately on top / elsewhere."

commit fcfc30439733d9922d2eedeec69e4ea704401e6e
Author: John Nichol <jnichol@google.com>

Add optional snap support to ScalingLazyColumn.

Move the Picker snap support to ScalingLazyColumnDefaults. Extend it to allow an offset to be applied when snapping. This is used if the developer wants to use Start Anchoring and make 2 list items "Straddle" the Viewport center line.

Bug: 217377069
Test: ./gradlew wear:compose:compose-material:connectedCheck --info --daemon
RelNote: "We have added snap support that can be used with ScalingLazyColumn. Set flingBehavior = ScalingLazyColumnDefaults.flingWithSnapBehavior(state) to enable snap support."
