Abnormal Base Fee

The current design of the Base Fee doesn't have MinFeePerGas. When there are many consecutive empty blocks, the fee per gas will decrease per block until to the minimal value of 8.

Another bad result is the eth_feeHistory response is also wrong. @xiaoch05

@AsceticBear What's the state of this?

[boundless-forest]

Waiting for sync prs from upstream.

Any updates?

[boundless-forest]

Sorry for the delay. After polkadot-evm/frontier#892 merged, we do not need the base-fee pallet anymore.

We can fix this after bumping the substrate version to 0.9.34+.
