Support androidx lifecycle

[sjudd]

When interacting with androidx Fragments and Activities, this change will use their corresponding Lifecycle objects to monitor their Lifecycle, instead of the custom RequestManagerFragments.

For now this just deprecates Glide's support for non-androidx Fragments and Activities. Ideally in a future version we'll remove those methods. However we may decide for backwards compatibility to retain the methods, but to remove their functionality. That would mean that the methods still exist, but they use the global RequestManager and do not provide any lifecycle integration.
