[PATCH 1/4] Maintainers.txt: split out section "ArmVirtPkg: modules used on Xen"

["Laszlo Ersek" <lersek@redhat.com>]

We ask contributors to copy Julien on patches that affect "Xen modules"
under ArmVirtPkg. With the "GetMaintainer.py" script being introduced
later, express this expectation in "Maintainers.txt" in machine-readable
format.

Notes:
    - Spelling out actual module names, in place of ArmVirtPkg/Library/Xen*
      and ArmVirtPkg/Xen* wildcards, makes for better readability in my
      opinion.
    
    - ArmVirtPkg/PrePi/ is shared with the ArmVirtQemuKernel platform, hence
      a section header that states "modules used on Xen", and not just "Xen
      modules" (as the latter might imply "Xen-only" modules).
