remove RHash::iter_lev.
iter_lev is used to detect the hash is iterating or not.
Usually, iter_lev should be very small number (1 or 2) so
`int` is overkill.
This patch introduce iter_lev in flags (7 bits, FL13 to FL19)
and if iter_lev exceeds this range, save it in hidden attribute.
We can get 1 word in RHash.
We can't modify frozen objects. Therefore I added new internal API
`rb_ivar_set_internal()` which allows us to set an attribute
even if the target object is frozen
if the name is hidden ivar (the name without `@` prefix).
