[new] ATOM-17253 Using AtomTressFX gem as an example to inject hair passes to main pipeline at run-time (#7661)
* Change AtomTressFX passes to write to exsiting DepthLinear buffer instead of creating a new one as output. Signed-off-by: Qing Tao <55564570+VickyAtAZ@users.noreply.github.com> * Added new api in RPI to apply render pipeline changes from FP Signed-off-by: Qing Tao <55564570+VickyAtAZ@users.noreply.github.com> * Update AtomTressFX gem to create hair parent pass at runtime Signed-off-by: Qing Tao <55564570+VickyAtAZ@users.noreply.github.com> * Change Scene::ApplyRenderPipelineChange() to TryApplyRenderPIpelineChanges(). Have TryApplyRenderPIpelineChanges() called automatically when a render pipeline is added to a Scene. Re-apply the render pipeline change when RenderPipeline got recreated (Pass hot-reloading support) Add AddPassBefore() and AddPassAfter() function to RenderPIpeline class.
