When DiagnosticEngine needs to diagnose something about an imported declaration, it uses ASTPrinter to print the declaration’s interface into a source buffer and then diagnoses it there. However, this code only printed public declarations, so it failed to account for features like `@testable import` which allow less-than-public declarations to be imported. Errors involving these declarations would therefore be diagnosed at <unknown>:0. This commit changes DiagnosticEngine to determine the access level of the declaration it needs to print and, if it is below `Public`, instead prints a separate interface whose minimum access level is low enough to include the desired declaration.
