[CF] Preliminary support for standalone builds.

This commit makes some preliminary fixes for standalone builds using
cmake. The standalone and Swift builds are similar, except for:
  * the CoreFoundation umbrella header,

  * ForSwiftFoundationOnly.h,

  * CFXMLParser.c and CFXMLNode.c, since these have CFTypeIDs that are
    present in CFRuntime_Internal.h behind DEPLOYMENT_RUNTIME_SWIFT, and

  * CFXMLInterface, since it refers to struct _NSCFXMLBridge, and this is
    defined in ForSwiftFoundationOnly.h.

Not present is a mechanism to refer to Block.h or dependent libraries.
