usb: typec: tcpm: Support native battery energy properties in battery AMS
Some fuel gauges report battery telemetry in energy rather than charge.
Add support for querying native energy properties for Battery Status and
Battery Capabilities AMS, falling back to calculating energy from charge
and average voltage when primary properties are not supported.
+---------+--------------------+----------------------------------+
| Sr. No. | Primary | Fallback |

| 1 | ENERGY_NOW | CHARGE_NOW + VOLTAGE_AVG |
| 2 | ENERGY_FULL_DESIGN | CHARGE_FULL_DESIGN + VOLTAGE_AVG |
| 3 | ENERGY_FULL | CHARGE_FULL + VOLTAGE_AVG |
+---------+--------------------+----------------------------------+
Note: All properties above are to be prefixed with POWER_SUPPLY_PROP_.
