CMake: Get rid of the Core_versiontagging object library

Browse Source 
We don't currently handle object libraries when creating prl files for
static Qt builds, so it's best to compile files as part of the main
Core target.

Use source file COMPILE_OPTIONS to add the -fno-lto flag to the
global/qversiontagging.cpp source file.

Amends 2d4a40f93f

Pick-to: 6.1 6.0
