This should be the final PR for the Hash Function series that is
trivial.
Of note: I decided to transform `HashMapTracedValues<Atom,..>` to use
FxBuildHasher. This is likely not going to improve performance as Atom's
already have a unique u32 that is used as the Hash but it safes a few
bytes for the RandomState that is normally in the HashMap.

Testing: Hash function changes should not change functionality, we
slightly decrease the size and unit tests still work.

FNV is faster for hashing less than 16 bytes of data and the
cryptographic properties of the default HashMap are not needed for the
various ids.
Testing: This does not change functionality.

This changes makes a variety of changes to ensure that the cursor is set
back to the default cursor when it leaves the `WebView`:
1. Display list updates can come after a mouse leaves the `WebView`, so
when refreshing the cursor after the update, base the updated cursor
on the last hovered location in the `DocumentEventHandler`, rather
than the compositor. This allows us to catch when the last hovered
position is `None` (ie the cursor has left the `WebView`).
2. When handling `MouseLeftViewport` events for the cursor leaving the
entire WebView, properly set the
MouseLeftViewport::focus_moving_to_another_iframe` on the input event
passed to the script thread.
3. When moving out of the `WebView` entirely, explicitly ask the
embedder to set the cursor back to the default.
Testing: This change adds a unit test verifying this behavior.
Fixes: #38710.

Properly send `mouseleave` events when the cursor moves between
`<iframe>`s. This allows a better handling of cursor changes and status
text updates. Specifically, we do not need to continuously update the
cursor and the value can be cached in the `Document`. In addition,
status updates can now be sent properly when moving focus between
`<iframe>`s.
Note that style updates for `:hover` values are still broken, but less
so than before. Now the hover state on the `Node` is updated, but for
some
reason the restyle isn't taking place properly. This maintains the
status quo as far as behavior goes when hover moves between `<iframe>`s.
This change also adds a helper data structure to `Document` which will
eventually be responsible for event handling.
Testing: Cursor and status change are currently very hard to test as
the API test harness makes this difficult at the moment.

Previously, when the theme was set it was only set on currently active
`Window`s. This change makes setting the `Theme` stateful. Now the
`Constellation` tracks what theme is applied to a `WebView` and properly
passes that value to new `Pipeline`s when they are constructed. In
addition, the value is passed to layout when that is constructed as
well.
Testing: this change adds a unit test.
