evaluator-rules: Pull in all missing rules from ORT's example rules

The evaluator rules in this repository have been created based on ORT's
example policy rules, meanwhile they deviated, but are quite redundant.
Reduce the deviation use-case-wise by copying all rules from ORT's
examples which are missing in this repository using ORT revision [1].

This is the first step towards making the 'ort-config' repository the
single dedicated place to examplify policy rules. In the following ORT's
example rules will be deleted, or rather minimized and turned into
functional test assets, see also [2].

Note: The copied rules have been created as part of [3].
