Completes the nullable migration for ICSharpCode.Decompiler/CSharp/Syntax: every hand-written file now carries #nullable enable. The pattern-matching API (INode/Pattern/PatternExtensions DoMatch/Match/IsMatch) takes a nullable 'other', since matching legitimately compares a pattern against a missing child. Members that genuinely return or accept null are annotated to match (AttributeSection's target token, IAnnotatable.Annotation<T>, Statement/Expression.ReplaceWith, SyntaxExtensions.GetNextStatement), and a latent null dereference in Backreference.DoMatch is fixed.
