[mathml] Use ASCII case-insensitiveness to validate mathsize and dir

The mathsize and dir attributes are defined modulo ASCII case-insensitive equivalence and are mapped to CSS font-size and direction properties [1] [2]. Since the CSS keywords are themselves defined modulo ASCII case-insensitive equivalence [3], there is not need to filter out other (Unicode) case-insensitive equivalent keywords (e.g. "ſmall") in the MathML Code, they will be rejected by the CSS parser. This CL replaces DeprecatedEqualIgnoringCase with EqualIgnoringASCIICase and adds tests to ensure that (Unicode) case-insensitive equivalent strings remain disallowed.
