Fix property getters to query hardware state instead of cached values

Browse Source 
- PROP_AUTO_EXPOSURE now queries hardware using IS_GET_ENABLE_AUTO_SHUTTER
- PROP_AUTO_GAIN now queries hardware using IS_GET_ENABLE_AUTO_GAIN
- PROP_GAIN_BOOST now queries hardware using IS_GET_GAINBOOST

This ensures each camera reports its actual hardware state rather than
a shared cached value when properties are queried via camera_control.py
