common: Add headers to support C++ style includes

Browse source 
When compiling existing libraries that are difficult to change, these
headers simplify the library's integration. This specifically was the
agreed upon fix for trying to compile Android's CHRE as a subsystem.
Making changes to the Android repo to use the C style includes would be
very difficult and would likely take a very long time.
