  MAINTAINERS: add Edgar as Xen maintainer

Add Edgar as Xen subsystem maintainer in QEMU. Edgar has been a QEMU
maintainer for years, and has already made key changes to one of the
most difficult areas of the Xen subsystem (the mapcache).

Edgar volunteered helping us maintain the Xen subsystem in QEMU and we
are very happy to welcome him to the team. His knowledge and expertise
with QEMU internals will be of great help.

I would like to be informed on changes made to the LoongArch virt machine.

I'm fairly familiar with Loongson-3 series platform hardware and doing
firmwre (U-Boot) development as hobbyist on LoongArch virt platform,
so I believe I can give positive review input to changes on that machine.

  target/loongarch/kvm: Add software breakpoint support

With KVM virtualization, debug exception is injected to guest kernel
rather than host for normal break intruction. Here hypercall
instruction with special code is used for sw breakpoint usage,
and detailed instruction comes from kvm kernel with user API
KVM_REG_LOONGARCH_DEBUG_INST.

Now only software breakpoint is supported, and it is allowed to
insert/remove software breakpoint. We can debug guest kernel with gdb
method after kernel is loaded, hardware breakpoint will be added in later.
