Unrolled build for #147832

Rollup merge of #147832 - aDotInTheVoid:rustdoc-format-options, r=GuillaumeGomez

rustdoc: Don't pass `RenderOptions` to `DocContext`

`RenderOptions` is full of HTML specific fields. The only ones that `DocContext` needs are `document_private` and `document_hidden`, which are accessable via `Cache` anyway.

Part of a larger campeign against `RenderOption`:
