Add controller scan filter options and refactor nimconfig.h

Browse Source 
* Add the option to change the scan filter mode through NimBLEDevice::setScanFilterMode

* Add the option to change the scan filter cache size through NimBLEDevice::setScanDuplicateCacheSize

* Refactor nimconfig to make it for doxygen use only.
