        [mathml] Add fuzz target for StretchyOperatorShaper

        This CL adds a new fuzz target [1] for the StretchyOperatorShaper class.
        It currently calls each API function but may need future adjustments.
        Using the corpus of math fonts from WPT [2] helps fuzzers find existing
        paths within StretchyOperatorShaper.
