debugger_visualizer: files not tracked in dep-info

[ehuss]

I tried this code:

#![debugger_visualizer(natvis_file = "foo.xml")]

along with a file named foo.xml in the same directory.

Compile this with cargo. Modify foo.xml. Try running a build again.

I expected to see this happen: Cargo rebuilds the project.

Instead, this happened: Nothing happens

The problem is that the debugger_visualizer file does not get added to the dep-info file.

The visualizer file does not get loaded into the SourceMap during parsing, so write_out_deps does not pick up on it. It's not clear yet what's the cleanest way to fix this.
