The domain capabilities data feature a firmware section which is filled
by few entries. The entries used until now looked real and it was
suspicious that a x86_64 host was listing aarch64 firmware images which
should not happen.
Fill it by an obviously fake path as it's not actually interpreted in a
meaningful way.

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.

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.

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.

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.

QEMU supports egl-headless if QEMU_CAPS_EGL_HEADLESS capability
is present. There are some additional requirements but those are
checked for in qemuValidateDomainDeviceDefGraphics() and depend
on domain configuration and thus are not representable in domain
capabilities. Let's stick with plain qemuCaps check then.

The feature is filtered by KVM and never automatically enabled. So even
though QEMU definition of EPYC-Rome contains this feature, the guest
won't see it. Also domain capabilities will show it as disabled for KVM
domains. Thus the feature should not really be included in our
definition of EPYC-Rome.
