e5ea4f9bdf LibWeb/HTML: Add source field to ToggleEventInit 
Corresponds to:
95131eec8f

As we now have a field in that dictionary, I removed the separate
`source` parameter from ToggleEvent::create(). Also updated the
relevant test.

50a79c6af8 LibWeb: Change SessionHistoryTraversalQueue to use Promises 
If multiple cross-document navigations are queued on
SessionHistoryTraversalQueue, running the next entry before the current
document load is finished may result in a deadlock. If the new document
has a navigable element of its own, it will append steps to SHTQ and
hang in nested spin_until.
This change uses promises to ensure that the current document loads
before the next entry is executed.

Fixes timeouts in the imported tests.

62ae4e878f LibWeb: Implement support for drawing with CanvasPattern 
We already had the API, but drawing to the canvas was not affected by
any created CanvasPattern. This moves CanvasPatternPaintStyle to LibGfx
so we don't have to reach into LibWeb, and implements the plumbing to
let Skia use images as a fill pattern.

9e9db9a9dd LibWeb: Store correct text offsets in PaintableFragment 
Previously, we were collapsing whitespace in Layout::TextNode and then
passed the resulting string for further processing through ChunkIterator
-> InlineLevelIterator -> InlineFormattingContext -> LineBuilder ->
LineBoxFragment -> PaintableFragment. Our painting tree is where we deal
with things like range offsets into the underlying text nodes, but since
we modified the original string, the offsets were wrong.

This changes the way we generate fragments:

  * Layout::TextNode no longer collapses whitespace as part of its
    stored "text for rendering", but moves this logic to ChunkIterator
    which splits up this text into separate views whenever whitespace
    needs to be collapsed.

  * Layout::LineBox now only extends the last fragment if its end offset
    is equal to the new fragment's start offset. Otherwise, there's a
    gap caused by collapsing whitespace and we need to generate a
    separate fragment for that in order to have a correct start offset.

Some tests need new baselines because of the fixed start offsets.

Fixes #566.
