Auto merge of #52257 - steveklabnik:refactor-rustdoc, r=QuietMisdreavus
Refactor rustdoc This is based on https://github.com/rust-lang/rust/pull/52194 and so shouldn't be merged until it gets merged. Now that plugin functionality has been removed, let's kill PluginManager. Additionally, rustdoc now follows the standard cargo layout instead of dumping everything at the top level. r? @rust-lang/rustdoc
