Finds the first character not equal to any of the characters in the given character sequence.

1) Finds the first character not equal to any of the characters of v in this view, starting at position pos.
2) Equivalent to find_first_not_of(basic_string_view(&c, 1), pos).
3) Equivalent to find_first_not_of(basic_string_view(s, count), pos).
4) Equivalent to find_first_not_of(basic_string_view(s), pos).
