examples: add blecent and bleprph similar to mynewt-nimble apps

These example apps create a BLE central and peripheral based on mynewt-nimBLE and work in companion. The apps are mostly based on their equivalents, which can be found at https://github.com/apache/mynewt-nimble/tree/master/apps Fix formatting Fix Makefiles Format function parameters Remove Doxygen comments Add more function names and bug fix Signed-off-by: Max Kriegleder <[email protected]>
