This is a follow-up of bug #8967. The implementation is self-explaining, the
only part which needs a comment is lyx2lyx: Since a 100% correct solution is
not possible, it has been decided not to switch amsmath off in the forward
conversion if no other ams command than \smash[t] and \smash[b] is used, but
to consider it a bug that older versions do not load amsmath automatically for
these commands. In the backward direction it is easy to keep the document
compilable, so just do that.
Math manual loads and save correctly it seems but expect some instability period.

- get rid of the cached Dimension. Text inset dimensions are saved in ParagraphMetrics and mathed maintain their own dimension where needed.
- width(), ascent(), descent(): deleted.
- dimension(): now needs a valid BufferView.
- metrics(): now void.
* BufferView::getCoveringInset(): simplify.
* ParagraphMetrics(): now cache inset dimensions.
