K2: Propagate explicit getter type to the property without initializer

In K1, we have the rules like:
- if there's explicit type of a property, then use it
- if there's an initializer, obtain its expression-type
- Otherwise, use getter's return type

The case when getter's type is implicit is handled at
FirDeclarationsResolveTransformer.transformProperty
