This change follows the pattern of
315dfe5865 by making strtofloat also
accept wchar_t* strings
(in addition to regular char*). It uses overloads from wctype_utils or
specialized functions to ensure comparison with literal characters (or
literal strings) pick char or wchar_t variants based on the argument
type.
The wcstof implementation is added, with unit test cases copied from
strtof test suite.
