Move llvm-readobj/StreamWriter to Support.

We wish to re-use this from llvm-pdbdump, and it provides a nice
way to print structured data in scoped format that could prove
useful for many other dumping tools as well.  Moving to support
and changing name to ScopedPrinter to better reflect its purpose.
