We have a Python script that needs to locate coredump path during
debugging so that we can retrieve certain metadata files associated with
it. Currently, there is no API for this.
This patch adds a new `SBProcess::GetCoreFile()` to retrieve target dump
file spec used for dump debugging. Note: this is different from the main
executable module spec. To achieve this, the patch hoists m_core_file
into PostMortemProcess for sharing.

Include the complete list of threads of all running processes
in the FreeBSDKernel plugin. This makes it possible to inspect
the states (including partial register dumps from PCB) of all kernel
and userspace threads at the time of crash, or at the time of reading
/dev/mem first.

Introduce initial support for using libkvm on FreeBSD. The library
can be used as an alternate implementation for processing kernel
coredumps but it can also be used to access live kernel memory through
specifying "/dev/mem" as the core file, i.e.:
lldb --core /dev/mem /boot/kernel/kernel

Introduce a FreeBSDKernel plugin that provides the ability to read
FreeBSD kernel core dumps. The plugin utilizes libfbsdvmcore to provide
support for both "full memory dump" and minidump formats across variety
of architectures supported by FreeBSD. It provides the ability to read
kernel memory, as well as the crashed thread status with registers
on arm64, i386 and x86_64.
