Make Gas Fees be tweakable by end users on Web3Auths panel

**Summary**
Unlike regular wallet providers, our web3auth wallet doesn't support speeding up the transaction execution by giving more gas to the transaction.

**Suggested features or ways to address the summary**
Add a UI/Dropdown in the w3a wallet that would ask users the amount of gas they'd want to provide for all the future transactions.

**Motivation**
- With the current setup, transaction execution is way slower and adding more money to fee does speed up the transaction, so we need to make it customizable

**Acceptance Criteria**

- [ ] Users can change the gas fee strategy based on the input field
- [ ] Transactions should be processed faster.
