[WIP] Set Sec-Fetch-Mode from the network service.

In order to move `Sec-Fetch-Mode` into the network service to ensure that it's consistently set every time `Sec-Fetch-Site` is set, this patch does a few things: 1. Based on the conversation in [1] and [2], this patch extends `network::mojom::RequestMode` to include two new values to represent nested navigations and object/embed navigations as distinct from main-frame navigations. 2. It introduces a new `network::IsNavigationRequestMode()` function to replace direct comparisons to `kNavigate` in various parts of the codebase. 3. It refactors `network::SetSecFetchSiteHeader()` into `network::SetFetchMetadataHeaders()`. This creates a single entry point from `URLLoader` to set all Fetch Metadata headers, and fleshes out the `Sec-Fetch-Mode` header.
