Add pv_get_property and create generic internal _get_property function. We need to use a similar function for pv and lv properties, so just make a generic _get_property() function that contains most of the required functionality. Also, add a check to ensure the field name matches the object passed in by re-using report_type_t enum. For pv properties, the report_type might be either PVS or LABEL. In addition, add 'const' to 'get' functions object parameter, but not 'set' functions. Add _not_implemented_set() and _not_implemented_get() functions.
