* pr/19556:
  Add profiles directly to the application environment for tests

Closes gh-19556

Prior to this commit, active profiles were being added to the Spring Boot
application environment by setting the `spring.profiles.active` property.
This could result in profiles getting parsed differently than other uses of `@ActiveProfiles`.
Setting the profiles directly in the `Environment` prevents this parsing.

Closes gh-19553

Fixes gh-19552

Prior to this commit, the `ErrorController` would override the original
error response status if the error map cannot be written due to content
negotiation with the HTTP client. In that case, the error handling
infrastructure returns a `406 Not Acceptable` response.

This commit improves the `ErrorController` so that
`HttpMediaTypeNotAcceptableException` instances thrown by that
controller are not returned as is but instead we write the error
response with an empty body and the original HTTP error status.
