Valentin Shergin 0332d475cc Fabric: Refined Yoga's isDirty flag management in YogaLayoutableShadowNode
Summary:
Motivation:
 * We never should call `markDirtyAndPropogate()` during tree construction/mutation because it might affect trees in different thread/dimentions;
 * In Fabric we basically always have to dirty nodes ourselves manually duting tree construction;
 * In Fabric we don't have "scoped/limited" tree mutations which require recursive dirtying; any mutation is creation of the new tree instance;
 * Default value of the `isDirty` flag is "false", so we have to change this right after creation of Yoga node (and after cloning).
