Add Binance Smart chain as main network

[churik]

Bug Report

Problem

Requested by users. Currently can be added as custom network, but have ETH as main currency and transaction history can't be loaded

Expected behavior

1. Can see correct balance of BNB
2. Can see transaction history
3. Can easily switch to Binance smart chain as it will be in the list of Main networks

Actual behavior

Reproduction

1. Open Status
2. Add custom network with params:
   URL: https://bsc-dataseed.binance.org/
   ID: 56

Additional Information

• Status version: release 1.17
• Operating System: Android, iOS

Basically, for any custom RPC chain we missing some optional params, which are using in MetaMask for instance (currency symbol, block explorer)

I believe it may be related to #12777 also, as we don't have blockcain explorer added on these chains (just an assumption)

Anyway, if custom RPC can work as it works in metamsk - that would be just awesome.

@qoqobolo dapps are fixed here #12791

@churik we don't use block explorers that's why history doesn't work, dunno might be @rasom could comment what we can do about that ,but most likely it depends on RPC if it supports methods we need for history or not
