[CMake] Move CLANG_ENABLE_(ARCMT|OBJC_REWRITER|STATIC_ANALYZER) into clang/Config/config.h.

LLVM_ENABLE_MODULES is sensitive of -D. Move them into config.h.

FIXME: It'd be better that they are #cmakedefine01 rather than #cmakedefine.
(#if FOO rather than #if defined(FOO))
Then we can find missing #include "clang/Config/config.h" in the future.
