Summary:
Fixes T11480. This cleans up the error logs a little by quieting three common errors which are really malformed requests:
- The CSRF error happens when bots hit anything which does write checks.
- The "wrong cookie domain" errors happen when bots try to use the `security.alternate-file-domain` to browse stuff like `/auth/start/`.
- The "no phcid" errors happen when bots try to go through the login flow.
All of these are clearly communicated to human users, commonly encountered by bots, and not useful to log.
I collapsed the `CSRFException` type into a standard malformed request exception, since nothing catches it and I can't really come up with a reason why anything would ever care.
Test Plan:
Hit each error through some level of `curl -H ...` and/or fakery. Verified that they showed to users before/after, but no longer log.
Hit some other real errors, verified that they log.

Summary:
Ref T1806. Ref T7173. Depends on D14047.
Currently, all exception handling is in this big messy clump in `AphrontDefaultApplicationConfiguration`.
Split it out into modular classes. This will let a future change add new classes in the Phacility cluster which intercept particular exceptions we care about and replaces the default, generic responses with more useful, tailored responses.
Test Plan:
{F777391}
- Hit a Conduit error (made a method throw).
- Hit an Ajax error (made comment preview throw).
- Hit a high security error (tried to edit TOTP).
- Hit a rate limiting error (added a bunch of email addresses).
- Hit a policy error (tried to look at something with no permission).
- Hit an arbitrary exception (made a randomc ontroller throw).
