Local scopedness is erased from IL and PDBs, so it can only be recovered
from the body. Compare each declaration initializer with later assignments,
field stores, and receiver captures using the C# 11 ref/value escape rules,
and emit scoped only when a later operation is strictly narrower.

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.

Comments and preprocessor directives were positional children interleaved
into the child list, and punctuation, keywords and operators were token-node
children. Add a leading/trailing trivia side-channel for comments and
directives, emit it from the output visitor, and re-home every comment
receiver onto it (including inside-block comments as comment-only empty
statements and undecodable attribute arguments as an ErrorExpression). With
locations and sequence points no longer sourced from token nodes, stop
reconstructing them on the locations path and delete CSharpTokenNode,
CSharpModifierToken and InsertSpecialsDecorator. The AST no longer carries
token children or positional comments; output is byte-identical.
