Summary:
Calculation of TransformedFrames was a method introduced by D37994809 (https://github.com/facebook/react-native/commit/64528e5faa445907b8287b412c344f30c20fca61) to fix rendering of inverted flat lists.
We found that this operation is crashing in fb4a causing the UBN T127619309
This diff creates a feature flag to disable the calculation of TransformedFrames in Layoutable ShadowNodes. **The goal of this diff is to revert the behavior introduced by D37994809 (https://github.com/facebook/react-native/commit/64528e5faa445907b8287b412c344f30c20fca61)**
The featureFlag is disabled in fb4a and enabled in react AR (because ReactAr apps relies on the calculation of TransformedFrames and these apps are not affected)
The root cause of the bug will be fixed by D38280674 (which still requires more testing and investigation)

Vertical and horizontal inversion was not taken into account in `computeRelativeLayoutMetrics`. To fix it, we precompute frames to include inversions.

Summary:
With the `MapBuffer`-based props calculated from C++ props, there's no need to keep `rawProps` around for Android views.
This change makes sure that the `rawProps` field is only initialized under the feature flag that is responsible for enabling `MapBuffer` for prop diffing, potentially decreasing memory footprint and speeding up node initialization as JS props don't have to be converted to `folly::dynamic` anymore.
For layout animations, props rely on C++ values, so there's no need to update `rawProps` values either.
Changelog: [Internal][Android] - Do not init `rawProps` when mapbuffer serialization is used for ViewProps.

Fabric's UIManager.measureInWindow didn't take viewport's offset into account. This diff fixes it by including viewport's offset in `LayoutContext`.

Use `Element<>` in `LayoutableShadowNodeTests`. It makes the tests cleaner and easier to understand.
