If a media element is in-tree with UNTRACKED visibility state, the information is incomplete, just ignore it.

In bug 1346987 we're attempting to remove uses of the
NS_OpenAnonymousTemporaryFile() in the content process as it sends a
synchronous IPC to the parent process on the main thread, which can cause UI
jank. This patch makes the MediaCache use the async anonymous temporary file
creation function added in bug 1346987.
The file descriptor is held by the FileBlockCache. This object buffers data
passed to it in memory, and defers writing of said data to another thread. I
added the async wait for the file descriptor to be inside that async "defer to
other thread" step.
This means that while the content process is waiting for the file descriptor to
come down from the parent process, we'll buffer media data being streamed in
memory. Given that our MSE implementation will buffer up to 100MB of media data
in memory anyway, it seems that more buffering in the src=url case while we
wait for an async IPC to do a round trip to the main process is acceptable.

<!-- Please describe your changes on the following line: -->
Before this PR, every object reflected in CSSOM is in `Arc<RwLock<_>>` to enable safe (synchronized) mutable aliasing. Acquiring all these locks has significant cost during selector matching:
* https://bugzilla.mozilla.org/show_bug.cgi?id=1311469
* https://bugzilla.mozilla.org/show_bug.cgi?id=1335941
* https://bugzilla.mozilla.org/show_bug.cgi?id=1339703
This PR introduce a mechanism to protect many objects with the same `RwLock` that only needs to be acquired once.
In Stylo, there is one such lock per process (in a `lazy_static`), used for everything.
I non-Stylo Servo, I originally intended to have one such lock per document (for author-origin stylesheets, and one per process for user-agent and user sytlesheets since they’re shared across documents, and never mutated anyway). However I failed to have the same document-specific (or pipeline-specific) `Arc` reachable from both `Document` nodes and `LayoutThread`. Recursively following callers lead me to include this `Arc` in `UnprivilegedPipelineContent`, but that needs to be serializable. So there is a second process-wide lock.
This was previously #15998, closed accidentally.

Fixes font shorthand serialization so that it serializes to "" when non-default subproperties are defined. These subproperties are those defined in #15033.
Adds tests:
- font_should_serialize_to_empty_if_there_are_nondefault_subproperties
- font_should_serialize_all_available_properties
The second test was previously commented out and underwent some cleanup to make it run.
