LaTeX writer: control figure placement with attribute (#11094)

If a `latex-pos` attribute is present on a figure, it will be used as the
optional positioning hint in LaTeX (e.g. `ht`).

With implicit figures, `latex-pos` will be added to the figure (and
removed from the image)  if it is present on the image.

Closes #10369.
