  workflows/release-binaries: Improve Windows installer (#220414)

The Windows WiX installer was missing two things for its setup:

1. The "product ID" which is used to uninstall any previous installed
LLVM versions. This avoids having versions living side-by-side with each
new release. I've reused the same GUID as the current 23.1.0 Win64
installer, to continue that "line" of product. The AArch64 installation
and any prior LLVM version (NSIS) before 23.1.0 will need to be
uninstalled manually, if we want to avoid side-by-side installatin.

2. A "per machine" scope which avoids messy installations which are
installed globally, but cannot be uninstalled globally, and available
only for the current user. After this PR, the installation is available
/ uninstallable to all users on the machine.

Since LLVM currently requires cmake 3.20 for building, and hasn't been
bumped yet to 3.31, also provide a workaround for the WiX scope setup.

Added a release note to signify that users would need to uninstall the
previous versions manually.

Assisted by Claude Opus 5.
