introduce the SDK nRF5 Peer manager into BLE security features

PM will be used for SoftDevices s13x, otherwise DM will be used.

Fix - security key distribution settings - Signing is not supported.

declare usage of encryption LTK and IRK if boonding enabled

deleted unused local reference to nRF5xGap class in bleGattcEventHandler.
fix PM internal bug (For gcc with -0s optimization an application fail to save a boonding data)
fuse redeclaration of PACKED macro in nRF5 SDK sources
