CMake: Make qt5_use_modules a macro, not a function.

Browse Source 
Because qt5_use_modules is a function that does a find package which
finds imported targets, things like this:

 qt5_use_modules(foo Sql)
 if (TARGET Qt5::Sql)
    message("Qt5Sql_FOUND: ${Qt5Sql_FOUND}")
 endif()

will show Qt5Sql as being not found, even though the target is in scope.

Fix that by making it a macro instead.
