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.

Each child of a C# AST node is declared as a [Slot] partial property, and the
source generator emits the accessor bodies and an ordered slot schema
(SlotCount/GetSlotRole/IsCollectionSlot) from them. Generating the schema
keeps slot order from being mis-stated by hand and lets a DEBUG invariant
check declared slot order against document order on every decompile. The node
hierarchy is converted family by family; the EntityDeclaration leaves flatten
their inherited Attributes/ReturnType/NameToken into each leaf's ordered slot
set. Storage stays the NRefactory linked list at this stage, so only the
declaration model changes and output is unchanged.

The "IL with C#" view decompiles each method body as a bare handle, so a
static constructor is decompiled without its type's field declarations in
the syntax tree. MoveFieldInitializersToDeclarations then could not find a
declaration to move the static-field-initializer statement onto, asserted
(kind was Static, not Primary) and dropped the statement -- crashing Debug
builds and silently losing the assignment in Release.
Dropping the statement is only correct for the primary-constructor case,
where the assignment's backing member is synthesized and has no separate
declaration. For static/instance initializers a missing declaration just
means the member is not part of this partial syntax tree, so the
assignment must remain in the constructor body.

Various improvements regarding primary constructor decompilation, including:
- introduce `HasPrimaryConstructor` property in the AST, as there is a difference between no primary constructor and a parameterless primary constructor
- improved support for inherited records and forwarded ctor calls
- exclude non-public fields and properties in IsPrintedMember
- introduce an option to always make the decompiler emit primary constructors, when possible
