Subject: [PATCH] Update Discord rich presence when the title changes

This allows us to update the rich presence description if a channel
is launched from the Wii Menu. It also handles other PPC title
launches, e.g. Smash Bros. Masterpieces.

Host.h: Added Host_TitleChanged().

DolphinNoGUI/MainNoGUI.cpp: Implemented Host_TitleChanged().
DolphinQt/Host.cpp: Implemented Host_TitleChanged().

Android/jni/MainAndroid.cpp: Stubbed Host_TitleChanged().
DSPTool/StubHost.cpp: Stubbed Host_TitleChanged().
UnitTests/StubHost.cpp: Stubbed Host_TitleChanged().
