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.

Only dumps the bare minimum memory content.
For example, the thread struct and stack of
the exception thread will be dumped.
Don't use this unless you want absolutely
minimum core dump.

Dumps the memory region between _image_ram_start[]
and _image_ram_end[]. This includes at least data,
noinit, and BSS sections.
This is the default.
