[roll] Roll fuchsia [fidl] Fix DisplayControllerImpl::CheckConfiguration return type.

This CL helps clarify both the return type of
DisplayControllerImpl::CheckConfiguration() and the use of the
ConfigDisplay -> ConfigCheckResult enum.

This CL also renames the ConfigDisplay enum to ConfigCheckResult,
because the old name is confusingly similar to the DisplayConfig struct
name.

Test: fx build (all clients are in-tree)
