Fix: Metamask relies on incorrect eth_ RPC endpoint for gas estimation

https://github.com/MetaMask/core/blob/f3636adffef458ed51eea454c6c4e006e1ef33b3/packages/gas-fee-controller/src/gas-util.ts#L123

eth_estimateGas RPC should not be used for 1559 estimations, instead eth_feeHistory should be used: https://github.com/ethereum/execution-apis/blob/main/src/eth/fee_market.yaml

Start in packages/gas-fee-controller/src/gas-util.ts around line 123 and inspect how the 1559 estimation path selects its RPC method. Compare the expected fee data with the execution-apis eth_feeHistory definition. Done means 1559 estimations no longer use eth_estimateGas and instead use the appropriate fee-history endpoint.
