Implement objc archiving in the crosstool. This involves a few steps:

1) In ExperimentalObjcLibrary, if static linking is required, signal CcLibraryHelper to create a static link action and pass in the necessary variables/link action input.

2) Add a new link type (Link.LinkTargetType.OBJC_STATIC_LIBRARY).  This involves changes to Link and LinkCommandLine.

3) For this new link type, implement static linking the OSX CROSSTOOL.  Also add tools in the crosstool package that point at libtool, which performs the archiving.
