chore: Revert "Revert "fix: scrollIntoView should respect scroll-margin (#8715)""

[nwidynski]

This PR refactors scrollIntoView and scrollIntoViewport to support scrollMargin, while working around the regressions mentioned in https://github.com/adobe/react-spectrum/issues/8689#issuecomment-3429792206. Additionally, a new inline & block option for alignment of a container element has been added.

By leveraging bounding rectangles, the internal calculations are now streamlined with DOMLayoutDelegate and significantly simplified.
