bazel syntax: consolidate syntax printing

The complete algorithm is now in NodePrinter,
rather than spread over dozens of files.
The only public API is Node.prettyPrint.

There is no change to the behavior,
and most of the code has merely moved.

Also:
- use StringBuilder, not Appendable: no more IOExceptions
- remove prettyPrint overload with indentLevel parameter
- rename FUNCTION_DEF to DEF
- hide some constants
