LibWeb: Add parse_integer_digits methods

Browse source 
The rules for parsing integers don't specify an upper bound on the
value that can be returned, so the `parse_integer_digits` method can be
used to check whether the given arbitrarily-large StringView is valid
according to these rules. The `parse_integer` and
`parse_non_negative_integer` methods would fail for values larger than
2147483647 when they shouldn't have.
