BT LE peripheral support for multiple same-UUID services

According to Bluetooth Core specification having multiple primary services with same UUID is valid scenario.

By the looks of it QtBluetooth does not support it because it internally uses a QMap of "service UUID => service data" to store the local (peripheral) services. This means that if a service with same UUID is added, it'll replace the previous one and the previous one gets kind of unreachable.
