ad3f33a992 qemu: add external backend for tpm
Introduce a new backend type 'external' for connecting to a swtpm daemon
not managed by libvirtd.

Mostly in one commit, thanks to -Wswitch and the way we generate
capabilities.

8db09767a9 conf: expose SGX feature in domain capabilities
Extend hypervisor capabilities to include sgx feature. When available,
the hypervisor supports launching an VM with SGX on Intel platfrom.
The SGX feature tag privides additional details like section size and
sgx1 or sgx2.

71d9836ca1 conf: Add channel devices to domain capabilities
As qemu becomes more modularized, it is important for libvirt to advertise
availability of the modularized functionality through capabilities. This
change adds channel devices to domain capabilities, allowing clients such
as virt-install to avoid using spicevmc channel devices when not supported
by the target qemu.

4e13cc4adb conf: Add USB redirect devices to domain capabilities
As qemu becomes more modularized, it is important for libvirt to advertise
availability of the modularized functionality through capabilities. This
change adds USB redirect devices to domain capabilities, allowing clients
such as virt-install to avoid using redirdev devices when not supported

2784a83907 domain_capabilities: Add vendor attribute for CPU models
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.

1445f62fce testutilsqemu: Fake TPM versions
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.
