…View Summary: ## Changelog: [General] [Added] - optionally calculate originFromRoot for ShadowNode and pass to ShadowView * If a LayoutableShadowNode calls `layout()` with `LayoutContext.includeOriginFromRoot==true`, all its (recursive) children will calculate `originFromRoot`. This will be needed for shared transition/view transition, where we'll later need to know the absolute position of a shadowNode/shadowView * if includeOriginFromRoot is false, there's no overhead of calculating `originFromRoot_` field * the way originFromRoot is calculated: we first initialize `originFromRoot_` on the LayoutableShadowNode that enables `includeOriginFromRoot` (using `LayoutableShadowNode::computeRelativeLayoutMetrics`, which traverses all the ancestors), then calculate originFromRoot for children in its subtree recursively (`LayoutableShadowNode::computeOriginFromRoot` which only calculates by the difference from immediate parent) Differential Revision: D89573536
Summary: ## Changelog: [General] [Added] - add UIManagerCommitHook::shadowTreeDidFinishTransaction Added this API so we can tell at end of Fabric mount phase which source the commit comes from. This is useful for identifying that a React update just gets mounted. * UIManagerMountHook::shadowTreeDidMount is called at similar timing however it doesn't include CommitSource information Differential Revision: D89573534
