Closes https://github.com/webstudio-is/webstudio/issues/5336
Adds a tooltip to the Transforms section `+` button when transforms are
unavailable for the selected element.
The Transforms section now stays visible but inactive for unsupported
elements, and the tooltip explains that transforms do not work with
`display: inline` and suggests changing display to `inline-block` or
`block`.
Also adds shared CSS data helpers for HTML replaced elements so the
transform availability check can distinguish regular inline elements
from replaced inline elements like `img`.
