[DOMException] add test cases of error names table

[kt3k]

This PR adds the test cases of error name to error code mapping of DOMException constructor. These cases are marked deprecated in WebIDL spec, but still part of web platform and should be tested. (ref: #27151 (comment))

closes #27151

Wow, this has actually found something very interesting. It appears that no browsers support "ValidationError", "NoDataAllowedError", or "DOMStringSizeError"! So we need to update the spec as well. Yay for test coverage!

In particular, the path is:

• Update https://github.com/heycam/webidl/ to remove those three from the table.
• Update this PR so that it tests that those values give 0, instead of their old numeric codes. It might be nice to group all these removed-from-implementation values in a separate section.
• Optionally, add new tests that all the non-deprecated DOMException names that have no legacy error code, i.e. "EncodingError" onward, also give 0.
