[gn build] Add build file for clang/lib/Basic and dependencies, 2nd try
Adds a build file for clang-tblgen and an action for running it, and uses that to process all the .td files in include/clang/Basic. Also adds an action to write include/clang/Config/config.h and include/clang/Basic/Version.inc. Differential Revision: https://reviews.llvm.org/D55847 (The previous commit of this contained unrelated changes, so I reverted the whole previous commit and I'm now landing only what I intended to land.) llvm-svn: 349679
