Message:

Widgets: Preserve classic sidebars when switching to a block theme.

When switching to a block theme, classic sidebars were orphaned and their widgets remapping to the 'wp_inactive_widgets' sidebar . This changeset preserves the sidebars and their widgets, providing a migration path to a block theme without losing the widgets.

Classic sidebars are now:

• Stored in a new theme mod called 'wp_classic_sidebars';
• Restored to the $wp_registered_sidebars global variable when the 'widgets_init' action fires (via a new internal function called _wp_block_theme_register_classic_sidebars());
• And marked as 'inactive' when interacting with sidebars REST API endpoint.

References:

• ​Gutenberg PR 45509 which adds an option for importing widgets from sidebars into template parts.

Follow-up to [50995], [6334].

Fixes #57531.
