* Fix corner cases of handling of Common Name fallback encoding Problem: - Appearance of a Mpid:/Mvid: in a DAC/PAI/PAA DN was deemed OK by previous code, but this caused a critical ambiguity in PAIs which would possibly cause fall-back to non-PID-scoped PAI interpretation. - Related to https://github.com/CHIP-Specifications/connectedhomeip-spec/issues/7470 - Fixes #28898 This PR: - Replaces the logic for fallback encodign conversion to take the first legitimate fully matching case for Mvid: and Mpid: and detect errors where either of these is present but without a following Mpid/Mvid. - Updates unit tests to improve coverage and to properly mark as invalid some cases marked invalid in spec which where deemed valid by prior code by mistake Testing done: - Integration tests still pass (relater to Commissioner DUT). - Test vectors updated. - New unit tests added. * Restyled by clang-format * Restyled by prettier-json * Address review comments by revamping algorithm * Fix leftover comment follow-ups from @bzbarsky-apple from #28899 * Restyled by clang-format * Add more comments and fix clang-tidy * Address more review comments --------- Co-authored-by: tennessee.carmelveilleux@gmail.com <tennessee@google.com> Co-authored-by: Restyled.io <commits@restyled.io>
