PANA-5681: Heatmaps

[jonathanmos]

What does this PR do?

Track ui elements with unique identifiers that are sent as part of the wireframes. Also send this identifier with taps and in this way correlate taps with views.

Important note: currently in the json schemas the new property permanent_id does not appear last in the ordering. This means that we would technically be breaking backwards compatibility by using the change this way - so a decision on this is necessary before the pr could be merged. If the schemas are updated then the pr needs to incorporate those changes.

Motivation

Support heatmaps on mobile.

Disambiguate root view identity across windows

When multiple windows are present (e.g., a dialog over an activity), buildRootCanonicalPath only prefixes the canonical path with appIdentifier/screenNamespace plus the root view path segment, but it does not incorporate any window-specific identifier. For root views like DecorView (no resource id, same class name), different windows on the same screen can yield identical root paths, which then produce identical permanentId values for corresponding view hierarchies. That breaks the “globally unique” guarantee and can merge heatmap taps across different windows. Consider including a window-specific token (e.g., window hash/z-order) or another root-unique discriminator in the root canonical path.
