QML: Remove Apply on Save functionality

The feature has been actually been disabled since commit ac771eb552e4,
but now it's time to also remove the dead code ...

Fixing the feature and bringing it out of the experimental state
would require quite some effort that apparently nobody is willing
to spend. So it's better to remove it.

The enablers in the qmldebug library, as well as the QmlJSDelta utility
class in qmljs library, are left in though.

-    If you change property values or add properties in the code editor, the
-    debugger can update the properties in the running application when you save
-    the file. This is enabled by default. To disable it, click the
-    \inlineimage qml-observer-bar-reload.png "Apply Changes on Save button"
-    (\uicontrol {Apply Changes on Save}) button on the toolbar.
-
-    \endomit
-
     When you change property values in the \uicontrol {QML/JS Console} or in the
     \uicontrol {Locals and Expressions} view, they are immediately updated in the running
     application, but not in the source code.
