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.
Why do we want to expose endianness, and what endianness to
expose? Endianness is a runtime bit state of CPUs. Sometime
this bit is hardwired but that is an implementation detail.
See commit 0e2c5647d92 and surrounding for MicroBlaze for
example.
