🎁 [Feature Request]: Account Abstraction for EVM template

[4meta5]

What is the feature you would like to see?

Steps:

1. Include ERC 4337 contracts + Paymaster contract(s) in EVM genesis state
2. Investigate implementation of custom UserOps mempool in Frontier. There are open source tx bundlers but compatibility has not yet been investigated

For the UserOps mempool (step 2), there is relevant ongoing work in polkadot-sdk for implementing meta-transactions:

• FRAME: Enable Meta Transaction for nonexistent accounts paritytech/polkadot-sdk#4511
• FRAME: Meta Transaction (pallet based version) paritytech/polkadot-sdk#4122
• FRAME: Meta Transaction (extension based version) paritytech/polkadot-sdk#3712
• Vision: Meta Transaction paritytech/polkadot-sdk#266
