Feature #13984: BigDecimal should be immutable/frozen and return itself on #dup

----------------------------------------
Currently, BigDecimal instances are not frozen, and supports #dup by returning a new instance.

In the spirit of #12979 and #13983, I think BigDecimal instances should always be frozen.
Then BigDecimal#dup/clone should just return the same instance.
