Add QtSortModuleDependencies.cmake

Browse Source 
The script produces the list of Qt submodules that are required to
build the submodules listed in the QT_BUILD_SUBMODULES variable.
Also the script supports the "collect all but skip repos" mode.
The repos that needs to be skipped should be specified by setting
BUILD_<repo>=FALSE.
The resulting list preserves the required build order.
