Add an API to specify groups of composables that should be treated as a focus group. ie, we give priority to the items within the group before we move focus to items outside the group.

Usecases:

Adjacent lists When we have two scrollable lists next to each other, we want to move focus among all the items of the first list before jumping to the next list. If we don't group all the items in a list into a focus cluster, then from the focus system's perspective the elements in both the lists are treated as siblings, and we move focus purely based on the location of the elements. This can lead to focus search to jump from the first list to the other one list to another before visiting all the items in a given list.
LazyLists When we reach the end of the lazylist, we need to ask the list to compose more items. However, if all the items in the LazyList are not treated as a group, after we visit all the visible items, we could potentially jump out of the list and move focus to another item because the focus system can't distinguish between items in a lazylist and items that are outside it.

Is there any update when the alpha04 will be available? We need it to target api 31 because of the PendingIntent mutability flags missing in alpha03.

Marked as fixed.

I'll schedule it for the next release. Note that alpha04 is a complete turn-down of the library where all APIs are marked as Deprecated, so you'll also want to start removing your usages of the library.
