Tezlink/node: run tezlink sandbox command

What

Allows to start the octez-evm-node sandbox in tezlink mode.

Why

At the moment the only way to test the node in tezlink mode is to run a network, either locally with the L1 sandbox or using teztcloud.

This will allow to leverage the run sandbox command of the l2 node.

How

We add a run tezlink sandbox command to the evm node. It forces the node to patch the node configuration and durable storage with the feature flag necessary to run in tezlink mode.

This reuses the same helpers as the run sandbox command, and has most of the same argument

Manually testing the MR

RUST_LOG=octez_evm_node_wasm_runtime::write_debug=trace  octez-evm-node run tezlink sandbox --data-dir sequencer --kernel <TEZOS_DIR>/evm_kernel.wasm --kernel-verbosity debug

Should run without crashing, and the kernel logs should show that it's running a Michelson VM.
