dedicated kernel docum. directory for Debug

Hi,

There is now a dedicated kernel debuggers/debugging sub-directory
(just added during the v6.12++ merge window):
  Documentation/process/debugging/.

There is currently only a little debugger/debugging documentation there
but if any of you know something that should be added there, please don't
hesitate to do so. (speaking for myself only)

thanks.
