Native: properly activate native methods/events

[AnnaShaleva]

Description

#4520 fixes false-positive activation in case if DeprecatedIn hardfork is passed. However, it's not enough for proper ActiveIn work because there's a case of false-positive activation in case if both DeprecatedIn and ActiveIn hardforks are not yet passed.

This commit rewrites ActiveIn condition: the method/event IS active if and only if ActiveIn hardfork IS active AND DeprecatedIn hardfork IS NOT active. ActiveIn hardfork IS active if it's null OR it's already passed. DeprecatedIn hardfork IS NOT active if it's null OR it's not yet passed.

For reference, here's the same condition (but in reversed form) in NeoGo:
