[PATCH 1/7] qemu_capabilities: Introduce QEMU_CAPS_THREAD_CONTEXT
In its commit v7.1.0-1429-g7208429223 QEMU gained new object
thread-context, which allows running specialized tasks with
affinity set to a given subset of host CPUs/NUMA nodes. Even
though only memory allocation task accepts this new object, it's
exactly what we aim to implement in libvirt. Therefore, introduce
a new capability to track whether QEMU is capable of this object.
