Add support for linea_estimateGas

[Julink-eth]

PR-Codex overview

Linea, a layer 2 blockchain, supports the Ethereum EIP-1559 gas price model, known for making transaction fees more predictable. Unlike the base Ethereum layer, Linea aims to offer a more stable and cost-effective approach to handling transaction fees. For detailed information, you can visit Linea's Gas Fees Documentation.

To further enhance the efficiency of transaction fee calculations, Linea has introduced a new RPC method designed to provide the best gas price estimates. This new method is documented in detail here.

The introduction of this new RPC method necessitates changes in how web3 libraries calculate gas prices. Traditionally, these libraries used the eth_gasPrice method. Linea's update shifts this approach to utilize the newly introduced linea_estimateGas method.

Detailed summary

• Added linea_estimateGas RPC method to calculate accurate gas price on Linea network
• Updated linea and lineaTestnet definitions to override fee calculation using linea_estimateGas
• Added lineaEstimateGas and lineaEstimateFeesPerGas actions to calculate gas and fees
• Updated types and imports related to fee calculation on Linea network
