Doc: Fix documentation macro and other issues

QDoc doesn't allow a macro that expands into an empty string:

  src/core/nodes/qcomponent.cpp:189: warning:
     Unknown command '\TODO'

Linking issues that are fixed by adding a dependency to Qt GUI:

  src/input/frontend/qkeyevent.cpp:121: warning:
      Can't link to 'QKeyEvent::nativeScanCode()'
  src/input/frontend/qkeyevent.cpp:141: warning:
      Can't link to 'QKeySequence::StandardKey'
  src/quick3d/quick3d/qquaternionanimation.cpp:42: warning:
      Can't link to 'QQuaternion'

Other fixed warnings:

  src/input/frontend/qmousecontroller.cpp:54: warning:
      Unknown command '\intantiates'
  src/quick3d/quick3d/qquaternionanimation.cpp:42: warning:
      C++ class Qt3DCore::Quick::QQuaternionAnimation not found
  src/render/materialsystem/qparametermapping.cpp:85: warning:
      Undocumented enum item 'UniformBufferObject'
      Undocumented enum item 'ShaderStorageBufferObject'
  examples/qt3d/wireframe/doc/src/wireframe.qdoc:28: warning:
      Can't link to 'BasicCamera'

+    The BasicCamera type is a trivial wrapper around the built-in \l Camera
     type that represents a virtual camera. It has properties for such things as
     the near and far planes, field of view, aspect ratio, projection type,
     position, and orientation:
