ApiAnnotations: work SourceText in for all integer literals

Certain syntactic elements have integers in them, such as fixity specifications, SPECIALISE pragmas and so on.

The lexer will accept mult-radix literals, with arbitrary leading zeros in these.

Bring in a SourceText field to each affected AST element to capture the original literal text for use with API Annotations.
