Even though several CPU models from various vendors are reported as
usable on a given host, user may still want to use only those that match
the host vendor. Currently the only place where users can check the
vendor of each CPU model is our CPU map, which is considered internal
and users should not really be using it directly. So to allow for such
filtering we now advertise the vendor of each CPU model in domain
capabilities.

Because of v8.5.0-rc1~25 we are already faking TPM support for
domaincaps. Might as well fake supported TPM versions.
The swtpm binary supports both TPM versions since its first
release, but pretend it isn't the case. For QEMU-5.2 and older
pretend only TPM-1.2 is available, QEMU-6.* has both TPM-1.2 and
TPM-2.0 and QEMU-7.0 and newer has only TPM-2.0 available.
This way, domaincaps are more dispersed.

Different CPU generations have different limits on the number
of SEV/SEV-ES guests that can be run. Since both limits come
from the same overall set, there is typically also BIOS config
to set the tradeoff betweeen SEV and SEV-ES guest limits.
This is important information to expose for a mgmt application
scheduling guests to hosts.

There are limits on the number of SEV/SEV-ES guests that can
be run on machines, which may be influenced by firmware
settings. This is important to expose to users.

The domain capabilities won't report TPM support unless SWTPM can be
initialized. To avoid relying on the swtpm install in the host, mock
the entire initialization method, since all it needs todo is return
a non-error value.

Currently we only have AMD SEV bits in qemu-2.12.0 replies which is way
too old to test new features that require AMD SEV as well.

Add the capabilities test data for the next qemu development cycle so
that we stay up to date.
Based on v5.2.0-1374-g9cd69f1a27
Notable changes detected by libvirt are the new machine types and
'intel-pt-lip', 'avx512-fp16', 'kvm-msi-ext-dest-id' cpu features
reported by qemu.
Other qemu changes not detected by libvirt include removal of the
'change' command, addition of 'sev-inject-launch-secret', 'yank',
'query-yank' commands and other device properties.
