Unify genesis initialization

[bkolad]

Description

This PR makes get_genesis_config as the exclusive method for generating a GenesisConfig. Prior to this change, tests/benchmarks and prover relied on the internal details of genesis_config.rs.

Currently, the code contains hard-coded paths to the token_deployer private key and genesis values for all modules. However, these hard-coded values will be updated in the upcoming PRs.
