Without this when static components are moved in editor they continue to write velocity after they stop moving.
This can be extra bad if the component was snapped to a final location so that it writes a bad velocity.

Tidy up use of FPrimitiveSceneProxy velocity getters.
Now DrawsVelocity() is only for velocity relevance.
And HasDynamicTransform() is for determining if we need to store previous transform state.
VSM caching was using PRIMITIVE_SCENE_DATA_FLAG_DRAWS_VELOCITY so replaced that with PRIMITIVE_SCENE_DATA_FLAG_SHOULD_CACHE_SHADOW which should use the old behavior and can be tweaked in future using ShouldCacheShadow().
A common pattern for determining whether to output velocity now is to check if a previous transform exists, and to OR in AlwaysHasVelocity().
I found some proxy types that don't check for previous transform.
Also I found that the debug physics aggregate types *never* check for previous transform.
These are pre-existing potential bugs for fixing in another pass.
Also I found some proxies that don't currently fill out velocity relevance.

Previously FScene contained an array of RT-shadowed lights which was updated when a light is added/removed.
However, this is incorrect as the light RT shadow state depends on CVars that may be changed dynamically.
The solution is to check if the scene currently contains any RT-shadowed lights during rendering. This is more expensive but robust.
The array of RT-shadowed lights is removed as it was not used beyond checking if it's empty.

Local light shadows are supported on mobile forward and deferred, need to enable full depth prepass to generate the ShadowMaskTexture.
Remove the 4 maximum local lights limitation on mobile forward.
Remove the "High Quality Reflection" on mobile forward.
Disable simple lights on mobile forward.

This change also remaps the original bEvaluateWorldPositionOffset on SMC into bEvaluateWorldPositionOffsetInRayTracing, because this var was only ever driven by ray tracing specific methods. The original bEvaluateWorldPositionOffset is now used by this more generic API.
Lastly, a new cvar (r.OptimizedWPO) has been added that indicates if the hint should be respected or not (default is false, which means WPO is always active, regardless of hint)

- Avoid extra copy and upload of transforms.
- Added FRayTracingGeometryInstance::BaseInstanceSceneDataOffset to skip creating an array of instance data offsets when they are continuous.
- Saves around 50MB on CitySample.

Rather than performing the change detection on the game thread, perform it only for the rendering primitive that might impact the path tracer. In particular, this avoids updates to the static meshes representing cameras. The camera transforms are handled on a per view basis, which means cameras not being moved will not have their output invalidated.

* Invalidate Path Traced output when component transforms change (this catches cases that don't re-create a primitive info object)
* Invalidate Path Traced output when light color or intensity changes
* Fix invalidation in a scene only affecting a single view (or view family). Instead of a single boolean, the scene now keeps a counter that ticks on changes and each view remembers the last value of this counter to detect changes.
