[mathml] Wrap <mtd> children in an anonymous <mrow>

This CL wraps the children of an \<mtd> cell within an anonymous \<mrow>.
That way, such children are laid out as if they were in an explicit
\<mrow>, in particular avoiding line breaks, performing operator
stretching and adding proper operator spacing [1]. In particular, this
fixes the second use case demonstrated at BlinkOn 16 [2].
