class LegacyHook
Defines a LegacyHook attribute object.
This allows contrib and core to maintain legacy hook implementations alongside the new attribute-based hooks. This means that a contrib module can simultaneously support Drupal 11 and older versions of Drupal that only support procedural hooks.
Marking a procedural hook as #LegacyHook will prevent duplicate executions of attribute-based hooks.
On older versions of Drupal which are not aware of attribute-based hooks, only the legacy hook implementation is executed.
