Extract header qtypes.h from qglobal.h
And move the related checks from qglobal.cpp to qtypes.cpp. This requires removing the unnecessary include statement for qglobal.h from qprocessordetection.h, that now needs to be included in qtypes.h. Task-number: QTBUG-99313 Change-Id: Ifd72b956326909be82c162f37854cad0878010e2 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
