Rework token prices

[sl1depengwyn]

Close #6547
Close #6855

Motivation

It happened that now we have no token price feature in master branch. Also, we sorted token balances by value that is not very useful for user. Additionally, we had issue of paginating balances of ERC-1155 or ERC-721 tokens when user have the same amount of different token ids of the same token

Changelog

To be able to sort and paginate token balances I implemented new token balance fetcher, changed pagination params for token balances, removed redundant functionality like manual sorting of token balance after fetching from the database since now the are fetching already in right order. Also, I removed KnownTokens module and functionality as new token price fetched does not use it.

Docs update blockscout/docs#117

@sl1depengwyn does it make sense to display price on "top tokens page" /tokens as well and make the same default sorting?

You mean sort by total supply * token price? In this case I think it make sense
