Revert "Add writer to emit the AST."
This reverts commit a753ad47a48fc0fba6e617b7ffcddc0e1fdc4b2e.
Reason for revert: This seems to be breaking `gn check` when the option is not enabled. Not sure why the preprocessor guard isn't working. Will fix and reland later.
Original change's description:
> Add writer to emit the AST.
>
> This CL adds a new `SyntaxTree` writer and a `dump-syntax-tree` option
> to the `tint` program which emits a copy of the AST to the terminal.
