[evm] refactor: Gas fee cap check was moved to ante handler. Remove or uncomment from VerifyFee

[Unique-Divine]

There's some dead code and/or misleading comments. This was pointed out in the Oct 2024 audit.

nibiru/x/evm/keeper/gas_fees.go

Lines 186 to 194 in 7dee8e0

	// gasFeeCapMicronibi := evm.WeiToNative(txData.GetGasFeeCapWei())
	// if baseFeeMicronibi != nil && gasFeeCapMicronibi.Cmp(baseFeeMicronibi) < 0 {
	// baseFeeWei := evm.NativeToWei(baseFeeMicronibi)
	// return nil, errors.Wrapf(errortypes.ErrInsufficientFee,
	// "the tx gasfeecap is lower than the tx baseFee: %s (gasfeecap), %s (basefee) wei per gas",
	// txData.GetGasFeeCapWei(),
	// baseFeeWei,
