[otbn] Better specify and describe errors

* Introduce a list of all errors that OTBN detects.
* Rename recoverable errors to software errors. In the future, software
  errors can be made recoverable, or fatal, depending on a config flag.
  (For now, all software errors are always recoverable.)
* Improve their description to better describe what caused the
  error. Do not give detailed reasons for the errors, as these reasons
  are about to be listed in the ISA documentation in much more detail.
* Reference this list as "authorative source" in other places, e.g. in
  the register table.
* Rename some errors to be more internally consistent.

Fixes #8238
