feat: fetch token rates across accounts

[bergeron]

Explanation

The TokenRatesController used to only fetch prices for tokens on the currently selected account. With this change, it will fetch prices for tokens across all accounts.

This will power UI features like showing portfolio $ values in the account picker, and avoids needing to re-fetch prices when switching accounts which causes some UI lag.

✅ Looks good to me.

Resolved my frontend PR to this and it seems to address the race condition nicely.

Went through it on the debugger and didn't run into a state where we didn't have enough market data to properly render & sort the list by descending fiat balance 👍
