Adds a NoPrefix associated type, to use for range() short-cuts in Map along with the EmptyPrefix marker. Just force the empty prefix in Map::range.

This type was missing from the impl. Adding it basically allows the added test case, where we iterate over a triple key without a prefix. Removed it altogether for simplicity.

Can be reviewed / merged independently of #432. Already integrated in #432 branch.

I see three useful no_prefix functions.

But since no prefix is always () / vec![], let's remove the argument, the extra trait type and just hard code it those 3 places.

Looks quite nice. Except for removing all the #[cfg(feature = "iterator")] everywhere.

Not sure how we can disable iterator (default) in cosmwasm-storage unless it is explicitly set. We should try to at least build the code without iterator enabled and ensure this works.

Please rebase on #438 (maybe after merge?) and fix any CI failures (due to iterator) before merge.
