Reword the description of threat #9 to make it more future-proof for
Arm CCA. By avoiding specific references to secure or non-secure
contexts, in favour of "worlds" and "security contexts", we make the
description equally applicable to 2-world and 4-world architectures.
Note that there are other threats that would benefit from such a
similar revamp but this is out of scope of this patch.
Also list malicious secure world code as a potential threat
agent. This seems to be an oversight in the first version of the
threat model (i.e. this change is not related to Arm CCA).

By nature, experimental features are incomplete pieces of work,
sometimes going under rapid change. Typically, the threat model
implications have not been fully considered yet.

- Add empty lines after titles.
- Reduce number of highlighting characters to fit title length.
- Remove most ``monospaced text``.
I think most of it looked weird in the rendered HTML version and
it had no obvious meaning.
