feature(report): enhance err html reporter

[sverweij]

Description

• make links from violation to the summary
• include all the rules, even those with 0 violations - hidden by default

Motivation and Context

• The links should make it easier to use.
• Including all the rules gives a completer picture. I also like to think it can help in the process of defining rules & adoption in teams.

How Has This Been Tested?

• automated non-regression tests
• additional unit tests

Types of changes

• New feature (non-breaking change which adds functionality)
