Update DeviceStateProviderImpl to read from device state config file.

This change introduces the device_state_configuration.xml file schema
and updates DeviceStateProviderImpl to read the set of supported states
from the configuration file. The file schema and provider only support
the lid switch condition, support for hinge angle will be added in a
follow-up change.

Test: atest DeviceStateProviderImplTest
Test: manual - place config on device and verify device state changes
with lid switch
