feat!: remove functionality that stops validators to opt-in on multip…

…le chains with same chain ID (#2249)

* refactor: move opt-in methods to partial_set_security.go

* refactor: move methods to power-shaping.go

* refactor: move ComputeNextValidators to validator_set_update.go

* handle error in test

* remove ProviderConsAddrToOptedInConsumerIds index

* make ComputeNextValidators return error

* remove logger from GetLastBondedValidatorsUtil
