errors: add config that lets user get more detailed exit codes

This adds an experimental config that lets the user get more detailed
exit codes. For example, there will be a specific error code for
input/user errors. This is part of
https://www.mercurial-scm.org/wiki/ErrorCategoriesPlan. I've made the
config part of tweakdefaults.

I've made the config enabled by default in tests. My reasoning is that
we want to see that each specific error case gives the right exit code
and we don't want to duplicate all error cases in the entire test
suite. It also makes it easy to grep the `.t` files for `[255]` to
find which cases we have left to fix. The logic for the current exit
codes is quite simple, so I'm not too worried about regressions
there. I've added a test case specifically for the "legacy" exit
codes.

I've set the detailed exit status only for the case of
`InterventionRequired` and `SystemExit` for now (the cases where we
currently return something other than 255), just to show that it
works.
