While a missing etag on a RESTBase wiki still indicates a problem,
we worked around these problems long ago in T233320 and we don't
really care about the logs any more, and the logging is now dominated
by requests on private wikis where etags are not expected.

For error responses, the response body should be JSON containing a
'detail' key with a human-readable error message.
Remove old debug logging for T233320, it's no longer needed and it
stopped working on WMF wikis anyway (again, previously it was broken
due to T234564).

ApiParsoidTrait depends on some ApiBase methods, which is inconvenient
when one wishes to access Parsoid HTML outside of the action API. Move
the bulk of the code into a new class ParsoidHelper, which doesn't.
Replace the uses of methods:
* dieWithError: throw a different kind of exception where it makes
sense, or change the method to return a StatusValue instead of
throwing where it doesn't
* getPageLanguage: use Title::getPageLanguage() or pass as parameter
* getConfig: pass to constructor
* getLogger: pass to constructor
* getRequest: pass the only required part to constructor,
leave some other API-specific code using it in ApiParsoidTrait
