fix(gnovm): in op_binary, return typed booleans where appropriate

[thehowl]

bool8.gno was failing, because the result of the == expression is an untyped boolean, while the first value is a typed boolean. This PR ensures that if either of the values in a binary expression is typed, we return a typed bool instead of an untyped bool.

I think the root cause for this is in preprocess stage, the untyped T is not correctly converted into the corresponding typed T.

It happens in func convertType, when t is nil or interfaceType, should use defaultTypeOf(t) as the dest t.

@ltzmaxwell thanks for the review!

I did some inspection and think I found a more correct fix. Can you take another look?

LGTM.
