QEMU 4.0.0 and newer automatically drops caches at the end of migration.
Let's check for this capability so that we can allow migration when disk
cache is turned on.

Update the capabilities from a non-upstream version (9c70209b63 is not
in qemu.git) to qemu upstream commit 33d6099906 (2019/06/18) so that we
get the QMP schema 'features' field support and are able to detect that
the 'file' block backend supports dynamic auto-read-only.
Note that I've rebuilt this on a machine with a more modern kernel and
microcode which exposes e.g. the recent CPU bug mitigations, thus I
opted to keep the CPU changes rather than trying to do a franken-caps
by updating only the output of query-qmp-schema.

We used type=full expansion on the result of previous type=static
expansion to get all possible spellings of CPU features. Since we can
now translate the QEMU's canonical names to our names, we can drop this
magic and do only type=static CPU model expansion.

When building QEMU command line, we should use the preferred spelling of
each CPU feature without relying on compatibility aliases (which may be
removed at some point).
The "unavailable-features" CPU property is used as a witness for the
correct names of the features in our translation table.

It is similar to "filtered-features" property, which reports CPUID bits
corresponding to disabled features, but more general. The
"unavailable-features" property supports both CPUID and MSR features by
listing their names.
