Remove the old deprecated ApplicationIPCManager IPC mechanism

The unit tests that needed an IPC side channel have been updated to use
intents instead.

-\section2 Inter-Process Communication (IPC) Extension

-The following snippet demonstrates how the \l{ApplicationIPCInterface} can be used to define an IPC
-extension. The IPC interface has to be defined in the System UI, for instance:
-
-\printuntil Component.onCompleted
-\printline }
-
-Here, a \c pi property is defined, as well as a \c computed signal and a \c circumference function.
-After registering this interface with
-\l{ApplicationIPCManager::registerInterface()}{ApplicationIPCManager.registerInterface()}, it can
-be used from the application processes.
-
-On the application side, the \l{ApplicationInterfaceExtension} type has to be used. Here's how
-App2 makes use of this interface extension:
-
-\quotefromfile applicationmanager/minidesk/apps/tld.minidesk.app2/app2.qml
-\skipto ApplicationInterfaceExtension
-\printuntil onPiChanged
-\printuntil /^\s{4}\}/
-
-The interface is used here as soon as it's ready. Of course, the interface can be accessed from
-elsewhere, too. The \l{ApplicationInterfaceExtension::name}{ApplicationInterfaceExtension.name}
-must match the name it was registered with in
-\l{ApplicationIPCManager::registerInterface()}{ApplicationIPCManager.registerInterface()}.
