Change edr_napi::provider::Response::solidity_trace to return a stack trace. This involves the following:

• Update the provider so that it returns a generated solidity stack trace. It should be only computed if there was an error during execution.
• Move all the logic that won't be exported anymore (vm tracer, decoder, solidity tracer, error inferrer) to edr_solidity and make them plain Rust code without references to NAPI.
