Brief of changes in this patch series:

- Improve argument parsing logic.
- Add few more easy to remember arguments.
- Add support to sign bunch of modules at once.
- Improve the help message with examples.
- Few trivial checkpatch reported issue fixes.
- Divide the modules_install task into sub tasks

Version 8 changes:
- Addressed comments from Masahiro Yamada
- Fix the bisect'ability error in patch 2.
- Fix missed out modules_sign_only issue.

Version 7 changes:
- Change Makefile.modinst and divide the tasks further

- This whole thing is done to facilitate bulk signing of modules
- Greg suggsted this idea here:
https://lore.kernel.org/all/2023060155-mustard-mating-32b7@gregkh/
- Thanks for the inputs Greg
- v7-0008-kbuild-modinst-do-modules_install-step-by-step.patch is fairly
big and I'm sorry about it. I created all patches considering build
stability in mind, so this can't be broken into pieces else in the
intermediate commit build will break.

Version 6 changes:
- Fix commit messages as suggested by Greg and David.

Version 5 changes:
- Addressed review comments from David Howells.
- Fragmented the patches into further small units.
