Use generalized bounding rect query hook

Recent change in <ResponsiveFrame /> made use of a custom hook that uses element.getBoundingClientRect() and ResizeObserver to get actual target element size. The hook returns a tuple [number | null, number | null]. In this PR I'm trying to resolve two things:

FacetController.test.js has been skipped due to ResizeObserver being unavailable in JSDOM environment. Moving the hook to a separate module enables us to use jest.mock() to 1) simply avoid the test failure 2) being able to configure the result of the hook (i.e. the "size") in tests.
Getting an element's size is just one of the cases of getBoundingClientRect() usage. I think we can benefit from generalizing (and simplifying) the hook to just return the bounding rect of an element. The rect includes required size fields along with coordinates. See https://developer.mozilla.org/en-US/docs/Web/API/DOMRect. Thus, we don't need to come up with custom signatures, simply using the existing general structures.
