feat(tee-key-preexec): support for onchain-compatible pubkey in report_data

[pbeza]

This PR is part of the effort to implement on-chain TEE proof verification. This PR goes hand in hand with matter-labs/zksync-era#3414.

I also removed this test as it is a duplicate of:

teepot/crates/teepot/src/ethereum/mod.rs

Lines 60 to 71 in afa524c

	// Decode the sample secret key, generate the public key, and derive the Ethereum address
	// from the public key
	let secp = Secp256k1::new();
	let secret_key_bytes =
	hex::decode("c87509a1c067bbde78beb793e6fa76530b6382a4c0241e5e4a9ec0a0f44dc0d3")
	.unwrap();
	let secret_key = SecretKey::from_slice(&secret_key_bytes).unwrap();
	let public_key = PublicKey::from_secret_key(&secp, &secret_key);
	let expected_address = hex::decode("627306090abaB3A6e1400e9345bC60c78a8BEf57").unwrap();
	let address = public_key_to_ethereum_address(&public_key);
	assert_eq!(address, expected_address.as_slice());

Ready to merge. 🫡
