Summary:
When configuration is set incorrectly (e.g., of the wrong type), detect and repair it by setting it to the default value. A setup warning will be raised separately.
Notably, this removes the need to hard-code all the class types.
This runs separately from the "invalid config" check because we need to run it on every page, but do setup checks only once per restart (some of them are slow).
Also dirty setup when we edit configuration.
Test Plan: Set config incorrectly on purpose, saw Phabricator correct it on restart and on every subsequent page load until it was fixed.

Summary:
- Allows us to implement setup warnings for edits which don't go through the web UI, e.g. "you edited a config file and set value X to something goofy".
- Allows us to implement more sophisticated validations, beyond basic type checks (e.g., "phabricator.base-uri" must be a URI).
- Fixes T358 (or, close enough -- fixes it for all options which have been migrated as per T2255.
Test Plan: Set "darkconsole.enabled" to "xyz" in my config, observed setup warning. Added fake validation, observed web UI edit error.
