Two changes fixed this. First we invert out the RateScale when calculating the PlayRate inside FAnimNode_SequenceEvaluator::UpdateAssetPlayer, since it get's multiplied back in the CreateTickRecordForNode function. This stops the jittering but the animation playback isn't scaled. To fix that we modify the Sequencer sections PlayRate by the asset'ss RateScale.

Poses & curves are now moved instead of copied where possible.
Also removed needless passing of bone space transforms to UAnimInstance::ParallelEvaluateAnimation, which further removes an extra allocation for sub-instances.

Fixed anim node details customization so that it respects code re-ordered parameters and ordering metadata.
Fixed EditCondition and (As Pin) indicators causing double-checkboxes.
Moved (As Pin) indicators to a right-aligned checkbox instead of right-aligning the label.
Reordered anim node properties: AnimDynamics, ApplyAdditive, BlendBoneByChannel.
Also manually resized the 'eye' icon (as it was box filtered form 40x40) & fixed up asymmetric padding for its checkbox style. This means 'public' checkboxes in Blueprints are now square!

Moved the work to acquire the bone transforms to PreUpdate on the game thread.
Supported master-pose by checking whether what we are copying is running master-pose (this potentially fixes issues where character heads/hats can detach).
Profiled, this averages ~8us on console per call, so not too bad.

Just in case - found a potential regression with the editor after this went in.
