d04ab82943 coredump: adjust mem_region find in gdbstub
Adjust get_mem_region to not return region when address == end
as there will be nothing to read there. Also, a subsequent region
may have that address as a start address and would be a more appropriate
selection.

1387e7c7c2 scripts: coredump: fix crashing on non-existent memory region
get_mem_region() may return None for a non-existent memory region
so we need to check first before looking at its properties.

49206a86ff debug/coredump: add a primitive coredump mechanism
This adds a very primitive coredump mechanism under subsys/debug
where during fatal error, register and memory content can be
dumped to coredump backend. One such backend utilizing log
module for output is included. Once the coredump log is converted
to a binary file, it can be used with the ELF output file as
inputs to an overly simplified implementation of a GDB server.
This GDB server can be attached via the target remote command of
GDB and will be serving register and memory content. This allows
using GDB to examine stack and memory where the fatal error
occurred.
