Support Compose 1.11 and deterministic subcomposition ordering

[zirman]

• Upgrade Compose dependency to 1.11.1.
• Update reflection logic in CompositionContexts.kt to support GapComposer, LinkComposer, and the RememberObserverHolder wrapper introduced in newer Compose versions.
• Implement deterministic sorting of subcompositions by child placement order using reflection to access LayoutNode.getChildren.
• Update instrumented tests to use v2 Compose test rules.
• Update expected test output to reflect internal Compose naming changes, such as ProvideCompositionLocals.

Thanks for this! Please write tests for subcomposition ordering, if at all possible.

I added a test but it's doesn't prove determinism. We have a large proprietary code base that we snapshot which is my real world test. So far these changes have generated the same order over multiple runs on different environments. I'm going to open a new PR since I broke this one from a force push when trying to sign commits. Thanks.
