PANA-5681: Integrate ViewIdentityResolver into Session Replay for heatmaps

[gonzalezreal]

What does this PR do?

Wires ViewIdentityResolver into Session Replay to populate permanentId on wireframes. This enables correlating wireframes with RUM action events for heatmap visualization.

Key changes:

• Adds public ViewIdentityProvider interface for Session Replay's view identity resolution
• Adapts internal ViewIdentityResolver (from RUM feature context) via ViewIdentityResolverAdapter
• Adds viewIdentityProvider to MappingContext for use by all wireframe mappers
• Populates permanentId in all wireframe types (Shape, Text, Image, Placeholder, Webview)
• Calls onWindowRefreshed() on each draw pass to index the current view hierarchy

Motivation

Support mobile heatmaps. This is the final piece connecting Session Replay wireframes to RUM actions.

Additional Notes

• Depends on PANA-5681: Integrate ViewIdentityResolver into RUM for heatmaps #3205
• Ported from PANA-5681: Heatmaps #3164. Also updates MappingContextForgeryFactory in session-replay-compose and session-replay-material test suites.

Review checklist (to be filled by reviewers)

• Feature or bugfix MUST have appropriate tests (unit, integration, e2e)
• Make sure you discussed the feature or bugfix with the maintaining team in an Issue

Avoid blocking feature-context reads in draw hot path

getViewIdentityResolver() calls getFeatureContext(Feature.RUM_FEATURE_NAME) with the default useContextThread=true; in DatadogCore.getFeatureContext this path submits work to the context executor and waits for the result synchronously. Because this helper is now used during on-draw snapshot capture (and also from image wireframe mapping), the render-time path adds avoidable cross-thread blocking lookups each frame, which can introduce jank on view-heavy/image-heavy screens.
