Skip deprecation period because it is very unlikely that anyone used this:
it does not appear anywhere on gerrit/git, no nontrivial google hits,
the documentation has been flat out wrong for 9 years and no one
noticed it, and the whole feature is fairly useless as you need to declare
it separately for every single exception class you expect.

* Actually use MWExceptionRenderer::AS_RAW. Use this after
an error is thrown while trying to pretty render the original
error. This is how this case was originally handled before.
* Do not show the google form or file cache in CLI mode.

* Make the error message itself be dumb/raw.
* Make the exception exposer show the same GUI message.
* Remove overzelous wgLang check in MWExceptionRenderer.

* This handles the work of showing exceptions so that
MWException does not have too.
* Simplify the DBError classes to regular Exception
classes. Lots of pointless prettification has been
removed, but DBConnectionError still gets the usual
special treatment of a fallback page and Google form.
* Remove hacky file cache fallback code that probably
did not work.
* Make MWExceptionHandler::report() wrap
MWExceptionExposer::output().
* Make MWException::runHooks() wrap
MWExceptionExposer::runHooks().
