When determining whether an imported initializer is a designated initializer, use the context it's being imported into.

Previously, we were using the context where the initializer was declared in Objective-C, rather than where it was being imported. This meant that we wouldn't treat an inherited designated initializer as a designated initializer if (for example) the designated-initializer marking came from our internal table of DIs.
