explorer: Eliminate getTokenLargestAccounts queries

[steveluscher]

Problem

Triton One reports that queries of this form:

{
  "method":"getTokenLargestAccounts",
  "jsonrpc":"2.0",
  "params":["EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v", {"commitment":"confirmed"}],
  "id":"b5c5071f-703a-4db6-85d9-90ec4e6102c9"
}

Are dysfunctional in that they:

1. Require that spl-token-mint be loaded on the RPC servers,
2. Even so, this results in 5 minute query times which is unusable to begin with.

Example: https://explorer.solana.com/address/EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v/largest

Proposed Solution

Remove all queries of this type from Explorer, like the ‘distribution’ tab on tokens.
