Xi Ge c403b140e1 ClangImporter: refactor ClangImporterOptions to be ASTContext-owned. NFC ...

We need ClangImporterOptions to be persistent for several scenarios: (1)
when creating a sub-ASTContext to build Swift modules from interfaces; and
(2) when creating a new Clang instance to invoke Clang dependencies scanner.

This change is NFC.
