qemu-replies-tool: Dump 'device-list-properties'

The order of properties in 'device-list-properties' can hange
arbitrarily and git is not great at picking the contexts in JSON to help
seeing what changed.

The new --dump-device-list-properties produces a stable order of
properties and dumps also the type and default value mainly useful for
comparing two .replies files.

Example output:

$ ./scripts/qemu-replies-tool.py tests/qemucapabilitiesdata/caps_9.0.0_x86_64.replies --dump-device-list-properties
