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.

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.

c32f172d12 qemu: wire up support for maximum CPU model
The "max" model can be treated the same way as "host" model in general.

f0a5cf4b8a cpu_map: Define and enable Snowridge model
Due to missing pdpe1gb support in the host CPU data, the CPU is still
incorrectly detected as Westmere-IBRS for host capabilities because we
don't have the option to disable features included in the base model
there.

919ff9debf domcaps: Report egl-headless graphics type
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.

3944f6855b cpu_map: Add Cooperlake x86 CPU model
The stepping range (10-11) is likely incomplete. QEMU uses 10 and the
CPUID data for Cooperlake show 11. We will update the range if needed
once more details about he CPU are available.

dd17a4eba8 cpu_map: Add more -noTSX x86 CPU models
One of the mitigation methods for TAA[1] is to disable TSX
support on the host system.  Linux added a mechanism to disable
TSX globally through the kernel command line, and many Linux
distributions now default to tsx=off.  This makes existing CPU
models that have HLE and RTM enabled not usable anymore.

Add new versions of all CPU models that have the HLE and RTM
features enabled, that can be used when TSX is disabled in the
host system.

On systems disabling the features without those types defined
in cpu-maps users end up without modern CPU types in the list
of usable CPUs to use in the likes of virsh domcapabilities
or tools higher in the stack like virt-manager.

This adds:
-Cascadelake-Server-noTSX
-Icelake-Client-noTSX
-Icelake-Server-noTSX
-Skylake-Server-noTSX-IBRS
-Skylake-Client-noTSX-IBRS

Introduced in QEMU by commit v4.2.0-rc2-3-g9ab2237f19 (function)
                  and commit v4.2.0-rc2-4-g02fa60d101 (names)
