Since we are now building introspection files for GLib while building GLib, so we want to make sure that we indeed load the freshly-built DLLs when running g-ir-scanner, so we add the various needed subdirs (and if needed, subprojects), to set the GI_EXTRA_BASE_DLL_DIRS envvar so that g-ir-scanner will look for the newly-built GLib DLLs. Ideally, upstream g-ir-scanner will need to be updated accordingly to do something similar to what we are doing here, but this is needed until the time that we require a g-ir-scanner that contains the update. This will also fix the g-ir-scanner erroring out when there is no pre-existing GLib on the system, as the needed DLLs are now found.
