monitor: Split mon_get_cpu fn to remove ENV_GET_CPU
The monitor currently has one helper, mon_get_cpu() which will return an env pointer. The target specific users of this API want an env, but all the target agnostic users really just want the cpu pointer. These users then need to use the target-specifically defined ENV_GET_CPU to navigate back up to the CPU from the ENV. Split the API for the two uses cases to remove all need for ENV_GET_CPU.
