Post merge local testnets (#3807)

## Issue Addressed N/A ## Proposed Changes Modifies the local testnet scripts to start a network with genesis validators embedded into the genesis state. This allows us to start a local testnet without the need for deploying a deposit contract or depositing validators pre-genesis. This also enables us to start a local test network at any fork we want without going through fork transitions. Also adds scripts to start multiple geth clients and peer them with each other and peer the geth clients with beacon nodes to start a post merge local testnet. ## Additional info Adds a new lcli command `mnemonics-validators` that generates validator directories derived from a given mnemonic. Adds a new `derived-genesis-state` option to the `lcli new-testnet` command to generate a genesis state populated with validators derived from a mnemonic.

+The `ETH1_BLOCK_HASH` environment variable is set to the block_hash of the genesis execution layer block which depends on the contents of `genesis.json`. Users of these scripts need to ensure that the `ETH1_BLOCK_HASH` variable is updated if genesis file is modified.
