Replace the blocking spin_processing_tasks_with_source_until calls
in apply_the_history_step_after_unload_check() with an event-driven
ApplyHistoryStepState GC cell that tracks 5 phases, following the
same pattern used by CheckUnloadingCanceledState.
Key changes:
- Introduce ApplyHistoryStepState with phases:
WaitingForDocumentPopulation, ProcessingContinuations,
WaitingForChangeJobCompletion, WaitingForNonChangingJobs and Completed
- Add on_complete callbacks to apply_the_push_or_replace_history_step,
finalize_a_same_document_navigation,
finalize_a_cross_document_navigation, and
update_for_navigable_creation_or_destruction
- Remove spin_until from Document::open()
- Use null-document tasks for non-changing navigable updates and
document unload/destroy to avoid stuck tasks when documents become
non-fully-active
- Defer completely_finish_loading when document has no navigable yet,
and re-trigger post-load steps in activate_history_entry for documents
that completed loading before activation

I believe the test regressions were previous false positives, that now
fail because we partially implement things instead of not implementing
them at all.
This now takes a registry directly. As a temporary stop-gap, the old
method on Document is still here and calls the new one.
We do get a test regression:
"Creating an element in a cloned document and inserting into the
document must not enqueue a custom element upgrade reaction" in
"custom-elements/upgrading.html".
Possibly a spec bug?
This begins implementation on form-associated custom elements.
This fixes a few WPT tests which I'm importing.

Previously, a crash would occur when attempting to throw an error in
this case because the method used to create the exception tried to get
the current realm from the execution context stack, which is empty. The
realm is now passed explicitly when constructing the error, avoiding
the crash.
This allows us to disable test output, which performs expensive assert
tracking. This was making our imported tests run significantly slower
than tests run via `WPT.sh`.
Formatting the output ourselves also allows us to remove unnecessary
information from the test output.
This commit also rebaselines all existing imported WPT tests to follow
the new format.
