Track mitigation for xen for CVE-2023-20593

Done this as xen ships in code changes accordingly to XSA-433.

While the maintainer lists for the xen upload:

   * Update to new upstream version 4.17.2, which also contains
     security fixes for the following issues: (Closes: #1042102)
     - x86/AMD: Zenbleed
       XSA-433 CVE-2023-20593
     - x86/AMD: Speculative Return Stack Overflow
       XSA-434 CVE-2023-20569
     - x86/Intel: Gather Data Sampling
       XSA-435 CVE-2022-40982
     - arm: Guests can trigger a deadlock on Cortex-A77
       XSA-436 CVE-2023-34320

there are no direct changes required in xen for the other issues.

If reviewers disagrees on this asessment it can be revisited.
