fix(editor) Honours Props For Fragment Components (#6165)

- `absoluteMoveStrategy` modified to handle the changed result from
`honoursPropsPosition`.
- Fixed `getFitness` function for convert to absolute and move strategy,
as it was returning a fitness above zero for a keyboard interaction.
- `keyboardAbsoluteMoveStrategy` modified to handle the changed result
from `honoursPropsPosition`.
- Fixed keyboard resize and move tests as they were using incorrect
element paths.
- `supportsAbsoluteResize` modified to handle the changed result from
`honoursPropsPosition`.
- `getMoveCommandsForSelectedElement` lost the invariants as they
weren't that necessary and were the cause of the browser tests
deadlocking.
- `getMoveCommandsForSelectedElement` is now a little more flexible if
the parent bounds are not available, as it's possible to move something
with a delta.
- Added `FrameWithFourPoints`, `rectangleToFourFramePoints` and
`FrameWithFourToSixPoints`.
- DOM walker now checks for descendants of valid paths to catch elements
inside fragments.
- `componentHonoursPropsPosition` now returns detail of what exactly the
component honours so that it's possible to get the detail of `position:
'absolute'` from this as well as the metadata.
- Both `componentHonoursPropsPosition` and `componentHonoursPropsSize`
now peak inside fragments at the root of their components.
- Fixed a bug in `propsStyleIsSpreadInto` where it wasn't covering
`props.style` being set directly.
- Added `metadataHasPositionAbsoluteOrNull` to make specifying certain
cases easier.
- Changed the default value for the position in
`emptySpecialSizeMeasurements` to `null`.
