Add ASCON

Add handling for ASCON

[abkarcher]

Hello,
Thank you for the contribution! Before I take a look at this, could you please remove the formatting/style changes unrelated to ASCON, and ensure consistent code style is used in the ASCON additions?

And then, if you could base this from the "libacvp_2_3_0-throttle" branch instead of main, that would be needed too.

Thanks again,
Andrew

Hello, sorry for the long wait.

I have done the changes as requested. Sorry again for the formatting, Emacs was more zealous with the autoformatting than I expected and I hadn't noticed it had changed the entire file.

Best regards,
Christoforos

Thanks! Taking a look now.

Thank you! I pulled a branch from this PR to do some more testing, and noted a few more things.

• I am hitting ACVP_INVALID_ARG errors when trying to build a registration for all ASCON algs. Something about acvp_cap_ascon_set_domain() is not functioning as expected. Instead of using switch case fall-throughs, can we restructure this to handle each PARM value for each cipher, similar to other algorithms?
• I do not think the ACVP_ASCON_MODE parameters or enums are needed; in each case we always have the ACVP_CIPHER value, unless I am mistaken
• The set_parm() and set_domain() ascon APIs for setting values should have bounds checks against ASCON_*_MAX values in acvp_lcl.h.
• Nit: (Sorry for not catching this the first go around): can we rename the ASCON params to have "parm" in the middle instead of the end? e.g. instead of ACVP_ASCON_PAYLEN_PARM, maybe ACVP_ASCON_PARM_PAYLEN? to be more consistent with other algorithms
