TON.TON ZRC-20 gasLimit should match contract const

[swift1337]

zq fungible list-foreign-coins --output json | jq '.foreignCoins[] | select(.symbol | contains("TON"))'
{
  "zrc20_contract_address": "0x54Bf2B1E91FCb56853097BD2545750d218E245e1",
  "asset": "",
  "foreign_chain_id": "2015141",
  "decimals": 9,
  "name": "ZetaChain ZRC20 TON Testnet TON",
  "symbol": "TON.TON",
  "coin_type": "Gas",
  "gas_limit": "21000", // should be changed
  "paused": false,
  "liquidity_cap": "0"
}

But in GW contract it's 17500: https://github.com/zeta-chain/protocol-contracts-ton/blob/053a6fd7fc1d5e7604a2359d5a06569aba0640fe/contracts/gateway.fc#L35

@morde08 bumping this

[swift1337]

AFAIK now this is configured in ZRC20, rather than in x/fungible cc @lumtis

Yes, the value in the foreign coin is not used at all, this value has been overlooked for a long time. I added the PR to deprecate the field but this would actually make more sense to just remove it since client should not read this value at all

[morde08]

@swift1337 So we'll eventually remove all of the gas_limit fields anyway so this issue can be closed yeah?
