Wire up the flags needed to support module libraries built and used with Swift. We need to pass `-bundle` to the linker when linking module libraries on Darwin, and we need to pass `-export-dynamic` to the linker when emitting an executable that exports symbols on Linux. This patch wires up `CMAKE_SHARED_MODULE_CREATE_Swift_FLAGS` and `CMAKE_SHARED_MODULE_LOADER_Swift_FLAG` on Darwin, and hooks up `CMAKE_EXE_EXPORTS_Swift_FLAG` on Linux in order to support passing things correctly. We can't expose `CMAKE_EXE_LINKER_FLAGS` to Swift, as it contains flags that the Swift compiler doesn't recognize, but the other language-specific variables are safe to expose.
