Mention gstreamer LIB variable for Windows
This got missed.
Ideally we'll get bootstrap to do all of this, but I haven't yet made
bootstrap work properly for Windows.

There are a few mentions of nsRuleNode left but they are mostly
historical references so it makes sense to keep them.

Fix private browsing mode preservation when loading URL
`Constellation::load_url` disregards the existing `BrowsingContext`'s `is_private` field when loading a new URL and creating a new `Pipeline` for the page load, which means that the `Pipeline` is always passed the public resource thread, even if its browsing context is in private browsing mode. This PR fixes that.

- [x] I'm not actually sure. I haven't found tests related to private browsing so maybe that's why this bug wasn't caught earlier?

Create ScriptMsg::GetBrowsingContextInfo
Script used to send two messages to constellation to first retrieve the id of the browsing context in which a pipeline resides and then its parent pipeline's id. This patch introduces a minor optimization to instead retrieve those fields in a single message.
Also, fixed a potential bug introduced in #21559 where if a browsing context wasn't found for a pipeline in response to `GetParentInfo` (which is now deleted), constellation sent nothing back, presumably causing the script thread to hang on the receiving channel.
