Joerg Bornemann d0911d0a92 CMake: Port the 'separate_debug_info' feature
For this, we have to uninline the separate_debug_info configure test,
because supporting the conversion of this in configurejson2cmake is not
worth the hassle.

Separate debug information can be turned on for a target by calling the
function qt_enable_separate_debug_info. For Qt's shared libraries and
tools separate debug information is generated if the
'separate_debug_info' feature is manually turned on.
