  -----------
  Host: generalise `GetXcodeSDKPath`

This generalises the GetXcodeSDKPath hook to a GetSDKRoot path which
will be re-used for the Windows support to compute a language specific
SDK path on the platform. Because there may be other options that we
wish to use to compute the SDK path, sink the XcodeSDK parameter into
a structure which can pass a disaggregated set of options. Furthermore,
optionalise the parameter as Xcode is not available for all platforms.
