Enable the use of wasmplus's `IsInactiveContract()` in cosmwasmAPI

[da1suk8]

In the dynamic_link branch separated process, the following function of wasmplus cannot be used in the #22 separated method due to circular reference problems.

Separation must be done by another method

wasmd/x/wasmplus/keeper/keeper.go

Lines 93 to 96 in 60fec8a

	func (k Keeper) IsInactiveContract(ctx sdk.Context, contractAddress sdk.AccAddress) bool {
	store := ctx.KVStore(k.storeKey)
	return store.Has(types.GetInactiveContractKey(contractAddress))
	}
