fix: skip optimize_save_restore_view for Animation handler_ops

Angular's ngtsc keeps restoreView/resetView in animation callbacks even
when the return value doesn't reference the view context (e.g.,
`return "animate-in"`). OXC was incorrectly removing these via
optimize_save_restore_view, causing 37 ClickUp component mismatches.
