ui/spice: Require spice-server >= 0.15.0

For major distributions we have now:

    Debian 13: 0.15.2
    Ubuntu 22.04: 0.15.0
    RHEL-9/CentOS Stream 9: SPICE is removed
    Fedora 42: 0.15.1
    OpenSUSE Leap 15.4: 0.15.0

Time to update the dependancy in QEMU and drop almost all
SPICE_SERVER_VERSION checks.
