Docs: Improve WP_List_Table and WP_Plugins_List_Table docblocks.

Improve the PHPDoc docblocks in `WP_List_Table` and `WP_Plugins_List_Table` for accuracy, completeness, and consistency with WordPress core documentation standards. Adds missing `@since` tags and corrects several existing versions, adds summary descriptions to all previously bare method and property docblocks, and refines type annotations with precise generic array types.

Developed in WordPress#10989.
Follow-up to r30679, r31127, r32642, r32654.
