Currently we only have AMD SEV bits in qemu-2.12.0 replies which is way

d53afa1e66 tests: qemucapabilities: Add test-data for the qemu-6.1 cycle
Add test data based on qemu commit v6.0.0-540-g6005ee07c3.

Notable changes are the removal of 'sheepdog' disk storage protocol.

Additionally the cpu model reported when probing seems to have changed
from:

"model-id": "AMD Ryzen 9 3900X 12-Core Processor            "

to:

"model-id": "QEMU TCG CPU version 2.5+"

despite building on the same machine. This probably also results in the
2 test changes in the CPU definition which popped up in this update.

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)

For each QEMU version there are usually several different,
architecture-dependedn scenarios that we're interested in testing;
however, since the test matrix has to be explicitly created by
calling DO_TEST_QEMU() multiple times with different arguments, we
end up with spotty coverage.

Fix this by implementing the arch-specific rules in code, which
result in the full coverage for a (version, arch) combo being
automatically achieved with a single call to DO_TEST_QEMU().
