FxHash is faster than FnvHash and SipHash for simple types up to at
least 64 bytes. The cryptographic guarantees are not needed for any
types changed here because they are simple ids.
This changes the types in script and net crates.
In a future PR we will change the remaining Fnv to be also Fx unless
there is a reason to keep them as Fnv.
Testing: Should not change functionality but unit test and wpt will find
it.

BroadcastChannel uses 2 hash maps in the constellation and they were not
kept properly in sync. Also fixed a logic error where
`Option<HashMap<...>>` was not considered empty when being `None`.
Testing: These warnings should not happen anymore:

broadcast router: (4,1)

Follow the specification and make OffscreenCanvas objects are
transferable,
but not in case if there are a weak reference to placeholder canvas
element.
To handle it properly need to implement dedicated frame
provider/dispatcher
between canvas element (script thread) and offscreen canvas (dedicated
worker thread).

Testing: Improvements in the following tests

According to specification ImageBitmap objects are serializable objects
and transferable objects.

In #36364 I moved both serializable and transferable implementations
from the `script_traits` crate into a single file called
`message_ports.rs`. Gregory raised the point that this was a bit of a
inaccurate grouping. This change attempts to fix it according to the
division in the specification.
See [the relevant thread on zulip][thread].

Testing: Covered by existing test as this is just code movement.
