DevTools: Modified LayerTree.compositingReasons to include a new property named compositing_reason_ids.

This change modifies the LayerTree.compositingReasons method [1] to include an additional return property named compositing_reason_ids. This new property provides an ID that can be used by CDP clients (such as the DevTools) to localize the compositing reasons.

The design was reviewed here in [2].

A separate CL will follow for the DevTools frontend to consume compositing_reason_ids and map them to strings that are localized in the frontend.
