pm: device: Dynamically add a device to a power domain
Add API to add devices to a power domain in runtime. The number of
devices that can be added is defined in build time.
The script gen_handles.py will check the number defined in
`CONFIG_PM_DEVICE_POWER_DOMAIN_DYNAMIC` to resize the handles vector,
adding empty slots in the supported sector to be used later.
