MathML: stop stretching all delimiters.

Browse Source 
No form? Reference: https://w3c.github.io/mathml-core/#dfn-form. The MathML processor is smart enough to determine whether the delimiter is prefix or postfix.

No stretchy/symmetric/fence in all cases? Reference: https://w3c.github.io/mathml-core/#algorithm-for-determining-the-properties-of-an-embellished-operator and https://w3c.github.io/mathml-core/#operator-dictionary-human (example entry: U+0028). Delimiters have the right properties by default.
