[nrfconnect] Extended DFU documentation about using mcumgr tool. (#7251)
Examples documentation about performing Device Firmware Upgrade
over BLE describes only case using Nordic mobile app. It would
be beneficial to have also documentation that shows how to perform
firmware upgrade from PC command line tool.
* Moved DFU description from examples to separate guide readme.
* Extended documentation by case using mcumgr command line tool
to perform DFU.
* Removed unnecessary part of the code allowing to advertise
over BLE with non conn type that was added in very early verison
of BLE Manager implementation.
