Add builtin definition for scanf, including extending the builtin encoding to
represent builtins that have the "scanf" attribution (via the format attribute) just
like we do with printf functions. Follow-up work is needed to add similar support
for fscanf et al.
This is to support format-string checking for scanf functions.
