feat: make eip2718 & eip1559 configurable in txpool

[lispc]

background:

circuit only support legacy tx but cannot support Typed Transaction Envelope tx. We plan to support non legacy tx within months. So here i disable non-legacy tx at txpool level but not consensus level. all the sequencers within months will be "non-evil", they will not deliberately produce blocks with Typed Transaction Envelope. So as long as we support non-legacy tx before scroll network becomes decentralied (i believe this), this PR is a good solution.

alternative solutions:
(1) disable London/Berlin. We will miss a lot of new features
(2) disable some related EIPs. I find it is not easy.. Forks and eips are coupled tightly in codes, and i think using this solution we need to modify much more codes and much more error-prone.

Add two configs in ChainConfig:
Only enable legacy (type 0x01 && 0x02 disabled):

"enableEIP2718" : false,

Only disable EIP-1559 (type 0x02 disabled):

"enableEIP2718" : true,
"enableEIP1559" : false,

Is it ok to disable params/config.go:IsBerlin() and params/config.go:IsLondon()?

This will disable Berlin Hard Fork and London Hard Fork, which would disable some other EIPs (may be useful).

Incompatibility issue: MetaMask chooses eip1559 when latest block header contains baseFeePerGas, so we let MetaMask send legacy tx by not setting baseFeePerGas in block headers.

Tested with MetaMask by switching the configs and restarting geth.

Ok, add --IsEIP2718Enabled --IsEIP1559Enabled in cmd line can be more convenient.
