Migrate to new CurrencyRateController

[Gudahtt]

The CurrencyRateController has been migrated to the BaseControllerV2 API, which includes various API changes. These changes include:

• The constructor now expects to be passed a RestrictedControllerMessenger.
• State changes are subscribed to via the ControllerMessenger now, rather than via a subscribe function.
• The state and configration are passed in as one "options" object, rather than as two separate parameters
• The polling needs to be started explicitly by calling start. It can be stopped and started on-demand now as well.
• Changing the current currency or native currency will now throw an error if we fail to update the conversion rate.

Manual testing instructions:

• Check that fiat is shown correctly when the extension starts
• Check that fiat values are shown correctly after the currency is changed in settings.
• Check that fiat values are shown correctly after switching networks
