[meta-security][DISCUSSION] : Enable Additional Security Configs in meta-security Layer

Hi Yocto Security Team,

I'm currently working with the Yocto Project and exploring the `meta-security` layer. I'd like to propose enabling additional security configurations to enhance system hardening.

Specifically, I'm looking to enable the following configurations:

- CONFIG_SLAB_FREELIST_RANDOM=y
- CONFIG_SLAB_FREELIST_HARDENED=y
- CONFIG_HARDENED_USERCOPY=y
- CONFIG_FORTIFY_SOURCE=y

I'd appreciate guidance on the best practices for integrating these into the layer, and whether there are any existing patches or recommendations from the community.

Please let me know if this is something that aligns with the goals of the `meta-security` layer, and how I can contribute or proceed further.

Thanks, and regards,
