Subject: [PATCH] qga-win: choose the right libpcre version to include in MSI
 package

According to GLib changelog [1], since version 2.73.2 GLib is using
libpcre2 instead of libpcre.  As a result, qemu-ga MSI installation
fails due to missing DLL when linked with the newer GLib.

This commit makes wixl to put the right libpcre version into the MSI
bundle: either libpcre-1.dll or libpcre2-8-0.dll, depending on the
present version of GLib.
