library/string.format.m:
We used to parse format strings, and pair up format specifiers with
the list of input poly_types, using semidet code, throwing
exceptions with generic messages if the semidet code failed.
This diff switches to using det code that returns a list of
situation-specific error messages. Since errors after the first
may be caused by the first error, we now throw exceptions whose
message is a detailed description of the first error, but that
decision is easily changeable.
Simplify some existing code.
