The benefit of this approach is that in a multi-core AMP system,
a single coredump might contain memory information from other cores.
By analyzing this coredump along with the corresponding ELF files from
the other cores, you can reconstruct the crash site of those other
cores.

If we have a full memory raw dump, we can parse g_tcbinfo, g_npidhash,
and g_pidhash from the ELF to get NuttX thread info,
regardless of the crash dump log file.
support new command in gdb:
info threads
thread id

stack dump add new region `show stacks`, but this script is not support
now this is fixed with adding check condition for all lines contains stack word

Need to distinguish between 32bit and 64bit registers, format the gdb reply message using struct.pack with correct format.
'<I' is used for 32bit registers, '<Q' for 64bit
Do not raise exeption for unrecognized registers in log, since they are
not used.

This adds support for multiple ELF files so that to help Kernel build
dump analysis with both nuttx and app ELF files.

This patch adds rv64 targets support and checked with gdb-multiarch
on Ubuntu. It also marks `-arch` parameter optional as it often can
be learnt from ELF file.

Additional information here:
- no code logic change, just add type hint
- make the code easy to work with
- minor python3 requirement without any complex type feature
