feat(plugins): Features plug-in, EIP-7702 mode

[marioevz]

🗒️ Description

Introduces a new pytest plugin called "features" which allows enabling a specific feature globally for all tests.

EIP-7702 Mode

Fills all tests with each deployed contract being a set-code-delegated account instead of an actual contract, i.e. the behavior of pre.deploy_contract changes to the following:

1. Deploy the requested code at some location A
2. Generate an EOA account B
3. Set storage of B to the requested initial storage (In case of normal allocation during filling, the storage is simply set in the dictionary, but if the test was to be executed on a live network, there would need to be a first authorization transaction to a contract which only purpose is to set the storage)
4. Create an authorization to set-code of B to A
5. Return address B

EOF V1 Mode

Fill all tests with each deployed contract (with unspecified EVM code type) set to EOF V1 code type, i.e. pre.deploy_contract now first checks if the parameter evm_code_type is unset, and if the provided deployment code is not already ethereum_test_tools.eof.v1.Container, and if so then wraps the code in an EOF container before setting/deploying the code.
