Add missing CorsController in settings's Application

[PVince81]

Description

Since "settings" is not an application but the app framework thinks it
is, it tries to resolve the namespaces to OCA. However we used OC for
all the controllers, so we need to register these explicitly into the
settings Application container.

Related Issue

None raised. Found by @phil-davis during QA of 10.0.4 RC1.

Motivation and Context

How Has This Been Tested?

Go to settings page, "Security" section. Add a whitelist domain for CORS.

Before fix: full page internal server error with exception about CorsController missing.
After fix: domain can be added.
