[drivers][power] add CLI helpers and current control support#11301

- add msh commands to inspect/operate power supplies and regulators
- expose snapshot/name helpers so shells and daemons can enumerate nodes safely
- add current support for regulator
- relax DM-only constraints in power/regulator stacks so basic builds work without DM/OFW
- solve the problem of enabling counting for regulator
