Rather than having each callside specifying the relevant
information from the GlobalScope, do this via a trait instead.
This would have saved us quite a bit of test debugging
since we would often forget to set relevant information
from the global context for a request.
Now, in the future when we need additional information from
the globalscope for a request, we only need to update this
method to make that happen.
Previously it would also sometimes use `document`, but
calling the relevant information on either `document` or
`globalscope` doesn't matter, since the `globalscope`
defers to the value from the `document` anyways.

This implements waiting for pending preloads, where the preload request
is still fetching the result when the second "real" request is started.
It is
implemented by storing responses in the `SharedPreloadedResources`
which is communicated via `PreloadId` send to the `CoreResourceManager`.

Replace NetworkError::Internal with structured enum variants
- Adds
UnsupportedScheme,CorsViolation,ConnectionFailure,Timeout,RedirectError,InvalidMethod,ResourceError,SecurityBlock,MixedContent,CacheError,InvalidPort,
LocalDirectoryError, variants in NetworkError enum.
- Refactored the usage of NetworkError::Internal(String) to use the
appropriate new variant
Testing: Changes does not require test.

In preparation for adding preload support for all requests, we need to
add relevant client information to all these entrypoints. Additionally,
for links we now also set the referrer correctly and initialize
documents. All of which are required to start loading preload
information when processing requests.

The `scripts_traits` crate was the only crate depending on `strum` with
the
`derive` feature. This accidentally allowed other crates to import strum
macros via `strum::` without declaring their own dependency on
`strum_macros`,
causing compilation issues when running `./mach test-unit -p net`.
This PR makes the imports consistent across the code base by:
- replacing all `strum_macro::` imports with `strum::` imports
- removing strum_macro dependencies
- adding derive feature to the strum workspace
Testing: Unit tests continue to pass

The goal of this change is to prevent having to copy so much data out of
listeners when a fetch completes, which will be particularly important
for off-the-main thread parsing of CSS (see #22478). This change has
pros and cons:
Pros:
- This makes the design of the `FetchResponseListener` a great deal
simpler.
They no longer individually store a dummy `ResourceFetchTiming` that is
only replaced right before `process_response_eof`.
- The creation of the `Arc<Mutex<FetchResponseListener>>` in the
`NetworkListener` is abstracted away from clients and now they just
pass the `FetchResponseListener` to the fetch methods in the global.
Cons:
- Now each `FetchResponseListener` must explicitly call `submit_timing`
instead of having the `NetworkListener` do it. This is arguably a bit
easier to follow in the code.
- Since the internal data of the `NetworkListener` is now an
`Arc<Mutex<Option<FetchResponseListener>>>`, when the fetching code
needs to share state with the `NetworkListener` it either needs to
share an `Option` or some sort of internal state. In one case I've
stored the `Option` and in another case, I've stored a new inner
shared value.
Testing: This should not change observable behavior and is thus covered
by existing tests.
Fixes: #22550

`FetchReponseListener` has traditionally lived in `net` even though it
is only used in `script` currently. Because of the two way dependency,
it has also use a lot of templating to implement something pretty basic
(call methods on a trait object).
This change moves the trait to `script` and removes several levels of
templating, making the code quite a bit shorter and easier to
understand.
This change is preparation for fixing #22550 and implementing
off-the-main-thread CSS parsing.
Testing: This should not change any behavior so is covered by existing
tests.

This aligns the request object more with the specification,
since the spec now has a `traversable_for_user_prompts` and
a separate field for the client. Before, they were present
in the same enum.
In doing so, new structs are added that are all required in
the new spec. With this we can add support for preloaded
resources in this client, which are only populated when
we have an applicable Global.
Since the spec moved things around a bit, it now has a
dedicated method to populate the client from the request.
Unfortunately none of the WPT preload tests pass, since
the requests are received out-of-order. The specification
requires us to wait for that to settle, but I haven't figured
out yet how to do that. Given that this PR is already quite
large, opted to do that in a follow-up.

This was missed during the previous implementation and was the reason
that the CSP tests weren't working.
It also updates a test to ensure that audio and video are not preloaded.
No browsers do that and with this fix, the test now passes in Chrome. In
Firefox it still fails as it doesn't implement `.vtt` support.

The Link HTTP header can do the same as link elements,
in that they can preload/prefetch/etc... This implements
the basics of header parsing and hooks it up for preload.
Note that we use a new nom-rfc8288 crate that implements
the parsing behavior. However, that crate is too strict
in that empty attributes (;; as part of the header) are
discarded and resulting in a parsing failure. Therefore,
we use its lenient parsing mode.
