Use Modular Controller Initialization in AssetsControllers

[darkwing]

A decision was made with regard to changing the initialization of all controllers from Core:

https://github.com/MetaMask/decisions/blob/main/decisions/core/0005-modular-controller-initialisation.md

All AssetsControllers need to be updated:

• AccountTrackerController.ts
• AssetsContractController.ts
• CurrencyRateController.ts
• NftController.ts
• NftDetectionController.ts
• TokenBalancesController.ts
• TokenDetectionController.ts
• TokenListController.ts
• TokenRatesController.ts ( Assigned to Salim )
• TokensController.ts

Extension example:

• Notification Controllers: feat: bump notification services controllers metamask-extension#31143
• Multichain Asset Controllers: fix: Update multichain controllers init metamask-extension#30294
• TokenRatesControllers: refactor: migrate tokenRates controller to modular controller init metamask-extension#31254

It is roughly 5-8 files per controller update.
