[core] Orchestration performance for styles with multiple sources
RenderOrchestrator holds a vector of ordered rendered layers,
in order to minimize calling of `getRenderLayer()`, which
could be quite expensive as it calculates hash of the layer Id.
This change improves orchestration performance in particular
for the styles that have multiple sources.
The `API_renderStill_multiple_sources` benchmark runs
approximately 70% faster with the changes applied.
