David Richardson f468d483ff AppKit, Foundation: Fix view archiving and add regression tests
Keyed archiving preserves view hierarchies created in code. Decoded views
retain their content, subviews and state, and each view class is verified
against its own description before archiving.

* CPAccordionView: Add CPCoding to CPAccordionView and CPAccordionViewItem.

* CPBox:
  * Encode the content, title and box views unconditionally.
  * Clear the superviews of the box and title views during decoding.

* CPButton: Initialize the value to CPOffState.

* CPMapTable: Add CPCoding.

* CPPopUpButton: Clear the inherited button value.

* CPSearchField: Update the cancel button when the object value changes.

* CPSplitView: Return nil from dividerColor when the theme defines no divider
  image.

* CPStepper: Discard the decoded buttons before recreating them.

* CPTabView:
  * Encode the current tab view items.
  * Exclude the tabs from the encoded subviews.

* CPTokenField:
  * Discard the decoded scroll view before recreating it.
  * Add the decoded tokens to the new document view.

* CPVisualEffectView: Resolve the backdrop filter property only when a DOM is
  available.

* CPBoxTest: Verify preservation of the content view, hierarchy and title, and
  decoding of an untitled box without warnings.

* CPButtonTest: Verify the initial value of a button.

* CPMapTableTest: Verify preservation of entries through archiving.

* DropInArchiveFixtures: Add populated view fixtures, tree comparison, and
  round trip and saved archive helpers.

* DropInArchiveGenerator: Save cib descriptions and view archives, and write no
  archive data if any view fails its round trip.

* DropInArchiveTest: Verify new archives, saved archives and reference cibs, and
  treat decoding warnings as failures.

* DropInSnapshot:
  * Describe the view hierarchy through private views, with state and content.
  * Add DropInWithFixedScrollerStyle.

* DropInArchives, DropInCibs: Add saved view archives, cib descriptions and
  reference cibs.

Saves the archive test data. Run this only against a build of main:
objj Tests/AppKit/DropInArchiveGenerator.j
It saves a description of what each reference cib produces. It then saves an
archive of each view fixture, with the fixture's description before archiving.
An archive is saved only if it restores that description, so a failure stops
the generator and no archive data is written.
