feat: migrate TokensController to BaseControllerV2

[cryptodev-2s]

Explanation

The TokensController has been migrated to BaseControllerV2. As part of this migration, the deprecated config property has been removed and has been replaced with flatten properties on the controller constructor (chainId, selectedAddress and provider).

PS: A migration is needed when using a new release of this controller.
