We already have 'QemuTargetInfo' struct which is used
with 'query-target', that should also be used with the
new 'query-targets' command.
We need to add the 'endianness' field to QemuTargetInfo.
I don't think that we need to report machines though.
We already have 'query-machines' which gives much broader
information on the machines. "MachineInfo" needs to
gain
"targets": ["SysEmuTarget"]
to list which target(s) a machine can be used with.
