Fix BIO_get_new_index() to return an error when it is exhausted.
Fixes #23655
BIO_get_new_index() returns a range of 129..255.
It is set to BIO_TYPE_START (128) initially and is incremented on each
call.
>= 256 is reserved for the class type flags (BIO_TYPE_DESCRIPTOR) so it
should error if it reaches the upper bound.
