  - Merge "PoolingContainer library" into androidx-main
  - PoolingContainer library
    
    This adds an androidx.customview:customview-poolingcontainer artifact that is
    depended on by both Compose and RecyclerView, through which AbstractComposeView
    and RecyclerView discover each other and communicate about when the Compose
    view should dispose its composition.
    
    This mechanism is independent of both Compose and RecyclerView, and
    could be used for any recycling container or child with heavy resources
    that should be retained across recycling.
    
    Relnote: "Add a new PoolingContainer library that allows for listening
    to dispose events of a container that manages its children outside the View
    hierarchy.  This will later be added as a dependency of Compose and RecyclerView"
    Test: New PoolingContainerTest
