* ATOM-16489 Add find passes functions for Scene or RenderPipeline in PassSystemInterface
Introduced new PassSystemInterface::ForEachPass() funtion to replace PassSystemInterface::FindPasses(), PassSystemInterface::GetPassesByTemplateName and ParentPass::FindPassByNameRecursive() functions.
Update all the places which were using those three functions.
The new pass finding filter support any combination of pass name, pass template name, pass class type, pass hirechary, owner scene, owner render pipeline.
Update unit tests.
