Update emphasis parsing for spec change.

Strong now goes inside Emph rather than the reverse,
when both scopes are possible.

The code is much simpler.

This also avoids a spec inconsistency that cmark had previously:

`***hi***` became Strong (Emph "hi")) but
`***hi****` became Emph (Strong "hi")) "*"
