qcacmn: Add configuration component header files

Add header files for the new converged configuration component.

cfg_dispatcher.h: Contains dispatcher lifecycle handlers
cfg_define.h: Tools for components to define new configuration metadata
cfg_ucfg.h: Contains APIs for consuming configuration at runtime
cfg_converged.h: Contains a collection of configuration metadata from
	all the converged components
