Adds OverscrollEffect#withoutDrawing and OverscrollEffect#withoutEventHandling

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.

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."

The following release(s) address this bug.It is possible this bug has only been partially addressed:

• androidx.compose.foundation:foundation:1.8.0-alpha06
• androidx.compose.foundation:foundation-android:1.8.0-alpha06
• androidx.compose.foundation:foundation-jvmstubs:1.8.0-alpha06
• androidx.compose.foundation:foundation-linuxx64stubs:1.8.0-alpha06

@sgibly We don't really need the app bar to adjust to its content height. What we are asking for is a way to configure the title based on expanded/collapsed state. TwoRowsTopAppBar provides a way to handle this, but is a private composable.

Our goal:

• use a slightly larger font size than the current default when in the expanded state
• allow the title to wrap 2 lines when in the expanded state
• confine the tile to a single line when in the collapsed state

As a workaround we have forked https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/material3/material3/src/commonMain/kotlin/androidx/compose/material3/AppBar.kt and added a convenience ExtraLargeTopAppBar composable that we use throughout our application: https://paste.googleplex.com/4926344363769856#l=100

Similar to this request, I would like to request just that the smallTitle field of TwoRowsTopAppBar is exposed in LargeTopAppBar, defaulting to the title composable. We currently are awkwardly manually handling the transition of large to small and back based on the collapsed fraction of the scroll state, but it seems like the title/smalltitle solution is already there and probably superior.

The problem that comes up with both rows of the TwoRowsTopAppBar being set to a large title is that on large font sizes/display sizes there is far too much white space for the invisible first app bar.

Added TwoRowsTopAppBar API here.

This should allow more flexibility when creating top app bars with two rows. We also previous made changes to support larger fonts in the app bars, so those changes should cover the rest of the request here (I hope :)).

Please let us know if you hit any issues.
