iio: add power and energy measurement modifiers

Add new IIO modifiers to support power and energy measurement devices:

Power modifiers:
- IIO_MOD_ACTIVE: Real power consumed by the load
- IIO_MOD_REACTIVE: Power that oscillates between source and load
- IIO_MOD_APPARENT: Magnitude of complex power

Signal quality modifiers:
- IIO_MOD_RMS: Root Mean Square value

Additionally adds:
- IIO_CHAN_INFO_POWERFACTOR: Power factor channel info type for
  representing the ratio of active power to apparent power

These modifiers enable proper representation of power measurement
devices like energy meters and power analyzers.
