feat: add new rates controller for non-EVM chains

[gantunesr]

Explanation

As part of the non-EVM initiative, there's a need to develop a new controller capable of fetching the rates for these blockchains. Currently, we can't rely on the CurrencyRatesController since it's dependent on the activity of the NetworkController, which is exclusively EVM oriented.

• ADDED: New RatesController to manage data related to rates for non-EVM blockchains
• ADDED: New method to use the multi price endpoint from CryptoCompare

Hello! I have done a single pass on this and made some suggestions on conventions. I will do another pass later thinking about tightening up the controller API and also diving more closely into JSDocs.

LGTM! (thanks for all those small changes)

Just a few more suggestions, mostly more naming-related things. All comment are minor at this point, everything is looking a lot better now.
