API Annotations: Keep track of unicode for linear arrow notationwip/az/unicode-hsscaled
The linear arrow can be parsed as `%1 ->` or a direct single token unicode
equivalent.
Make sure that this distinction is captured in the parsed AST by using
IsUnicodeSyntax where it appears, and introduce a new API Annotation,
AnnMult to represent its location when unicode is not used.
