Provide a way to define GAP/GATT services for central roles

Some devices require the Generic Access (GAP) and Generic Attribute (GATT)
services to be defined. Otherwise they refuse a proper interaction.
This is done implicitly by Android and BlueZ. The reason why BlueZ does
not do this for QtBluetooth is because QtBluetooth sets up its own GATT
infrastructure.

Normally a QLEController in central role cannot do that via public API
as the QLEController::addService() function blocks on peripheral use
cases. This patch sets the profiles up.

In the future the feature really requires a better form of API
(beyond the above env variable) or should be enabled by default
but since we need this earlier than Qt 5.10 a more subtle
approach was chosen. For now the feature can
only be enabled if the QT_DEFAULT_CENTRAL_SERVICES was set.

Another limitation is that the characteristics of the added services
are completely static.
