rustdoc: Switch to mainline rayon

Browse source 
The rustc fork of rayon integrates with Cargo's jobserver to limit the
amount of parallelism. However, rustdoc's use case is concurrent I/O,
which is not CPU-heavy, so it should be able to use mainline rayon.

See this discussion [1] for more details.

Note: I chose rayon 1.3.1 so that the rayon version used elsewhere in
the workspace does not change.
