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.

For finding the best matching CPU model for a given set of features
while we don't know the CPU signature (i.e., when computing a baseline
CPU model) we've been using a "shortest list of features" heuristics.
This works well if new CPU models are supersets of older models, but
that's not always the case. As a result it may actually select a new CPU
model as a baseline while removing some features from it to make it
compatible with older models. This is in general worse than using an old
CPU model with a bunch of added features as a guest OS or apps may crash
when using features that were disabled.
On the other hand we don't want to end up with a very old model which
would guarantee no disabled features as it could stop a guest OS or apps
from using some features provided by the CPU because they would not
expect them on such an old CPU.
This patch changes the heuristics to something in between. Enabled and
disabled features are counted separately so that a CPU model requiring
some features to be disabled looks worse than a model with fewer
disabled features even if its complete list of features is longer. The
penalty given for each additional disabled feature gets bigger to make
longer list of disabled features look even worse.

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
