fb5a246424 qemu: capabilities: Probe QEMU_CAPS_SMP_DIES from the QMP schema
The configurability of the number of dies in a CPU can be inferred from
the presence of the 'die-id' field in 'query-hotpluggable-cpus'.

067f44fd0b qemu: capabilities: Probe 'discard' and 'detect-zeroes' from 'blockdev-add'
Probing QEMU_CAPS_DRIVE_DISCARD and QEMU_CAPS_DRIVE_DETECT_ZEROES can be
replaced by looking into the QMP schema rather than looking at -drive
which isn't in use any more.

42e7f6a35b scripts: group-qemu-caps: Add capability name as comment to capability string
Add a cross reference of the enum value name with the string
representation. This allows a quick cross-reference of the values
without having to open the header and implementation files separately.

To achieve this the checker code at first obtains a list of the
flags and cross-references them when checking the grouping in
syntax-check, thus we are guaranteed to stay in sync.
