docs(auth): add more information about CoTs

Explain that platforms are free to define their own Chain of Trust (CoT)
based on their needs but default ones are provided in TF-A source code:
TBBR, dualroot and CCA.

Give a brief overview of the use case for each of these CoTs.

Simplified diagrams are also provided for the TBBR and dualroot CoTs -
CCA CoT is missing such a diagram right now, it should be provided as a
future improvement.

Also do some cosmetic changes along the way.
