qemu-replies-tool: Dump 'qom-list-types'

Browse Source 
The order of entries in 'qom-list-types' sometimes changes arbitrarily.

The --dump-qom-list-types produces a stable order and drops the for
libvirt unneeded 'parent' information.

Sample output:

$ ./scripts/qemu-replies-tool.py tests/qemucapabilitiesdata/caps_9.0.0_x86_64.replies --dump-qom-list-types
(qom) 486-v1-x86_64-cpu
(qom) 486-x86_64-cpu
(qom) AC97
(qom) AMDVI-PCI
(qom) Broadwell-IBRS-x86_64-cpu
(qom) Broadwell-noTSX-IBRS-x86_64-cpu
(qom) Broadwell-noTSX-x86_64-cpu
(qom) Broadwell-v1-x86_64-cpu
(qom) Broadwell-v2-x86_64-cpu
(qom) Broadwell-v3-x86_64-cpu

Dumps all types returned by 'qom-list-types' in a stable order with the
'parent' property dropped as it's not relevant for libvirt.
The tool can be also used to programmaticaly modify the '.replies' file by
editing the 'modify_replies' method directly in the source, or for
