build(tbbr): drive cert_create changes for cca CoT
The build system needs to drive the cert_create tool in a slightly
different manner when using the cca chain of trust.
- It needs to pass it the plat, core_swd, and swd ROT key files.
- It must now generate the cca, core_swd, and plat key certificates,
and exclude the non-relevant certificates.
