In b/168524931 we globally added a delay before emitting a PressInteraction in case we are in a scrollable container, and in case the 'down' event is actually part of a scroll. This is important so that we don't show a ripple if the user is actually beginning a scroll motion.

However, currently because we don't have any 'in scrollable container' metadata, this is globally enabled, whether or not we actually need to delay. This has the unfortunate effect of delaying PressInteractions unnecessarily, and hence causing ripples and other indication to be delayed and feel laggy.

With the recently added ModifierLocal APIs, we can now provide and consume this metadata, so we should now implement support for this so we only delay PressInteractions if necessary.

Compose work:

Add ModifierLocal to represent scrollable container metadata
Set this metadata inside Modifier.scrollable - this is used in other APIs such as lazy lists and Modifier.verticalScroll, so just setting it here should cover all cases.
Consume this metadata where we currently delay PressInteraction, so that we only delay if we are truly inside a scrollable container

Interop work:

We also need to pass down whether the parent ComposeView is in a scrollable container, as even if there are no scrollable containers in the Compose part of the hierarchy, if the ComposeView itself is in a scrollable ViewGroup, we should still delay presses
AndroidViewHolder should also consume this metadata and use it to override ViewGroup#shouldDelayChildPressedState(), so any Views hosted inside of Compose can also delay their pressed state if they are inside scrollable Compose containers, or inside non-scrollable Compose containers inside a non-scrollable AndroidView inside a scrollable Compose container...

Because the interop work requires APIs between ui and foundation (presumably the ModifierLocal needs to be public API in ui, so we can use it from foundation), for now we can just ignore the AndroidViewHolder support, and just query LocalView instead of setting this metadata at the ComposeView layer to unblock the most common cases.
