Need new TCK tests for URI Path Canonicalization

[pmd1nh]

Servlet 6.0 had a clarification for the decoding and normalization of URI paths

As a result, section 3.5.2 URI Path Canonicalization was added to Servlet 6.0 Specification

However, there is no TCK test in this area.

Greg had a unit test but I think a formal TCK is needed.
