My brief reading of this function implies that this whole function will only get
called for component builds. Do we need this extra check?

+    # The use of source sets in gn builds means that references to some extra
+    # DLLs get pulled in to setup.exe. Unpacking these to |installer_dir| is
+    # simpler and more robust than switching setup.exe to use libraries instead
+    # of source sets.
