7826148a72 qemu: report max number of SEV guests
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.

34cb8f6fcd conf: extend domain capabilities for max SEV guest count
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.

6e1baedd2f qemu: mock swtpm initialization in tests
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.

0b0a633d1a tests: add AMD SEV bits into qemu-6.0.0 replies
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.

5138a09260 qemu: report whether a CPU model is deprecated in dom capabilities
QEMU has the ability to mark CPUs as deprecated. This should be exposed
to management applications in the domain capabilities.

This attribute is only set when the model is actually deprecated.
