Implement several EntityRegistry.cs features for the C# ilasm replacement: - Add ClassLayout table emission: parse .pack and .size directives, emit AddTypeLayout for types with explicit packing or size - Add FieldLayout table emission: parse [offset] syntax on fields, emit AddFieldLayout for fields with explicit offsets - Add FieldRVA table emission: wire .data declarations to fields with 'at' syntax, emit AddFieldRelativeVirtualAddress - Implement GetPinnedType for pinned type signature encoding - Build full assembly-qualified names for type references with Version, Culture, and PublicKeyToken - Fix float32/float64 missing from VisitSimpleType switch - Fix core assembly resolution to match native ilasm: prefer System.Private.CoreLib, then System.Runtime, then mscorlib, then netstandard, with fallback to creating mscorlib reference. Also fix AssemblyRef table emission and dictionary key comparison. - Add tests for ClassLayout, FieldLayout, FieldRVA, and core assembly resolution functionality

Implement several EntityRegistry.cs features for the C# ilasm replacement:
Add ClassLayout table emission: parse .pack and .size directives, emit AddTypeLayout for types with explicit packing or size
Add FieldLayout table emission: parse [offset] syntax on fields, emit AddFieldLayout for fields with explicit offsets
Add FieldRVA table emission: wire .data declarations to fields with 'at' syntax, emit AddFieldRelativeVirtualAddress
Implement GetPinnedType for pinned type signature encoding
Build full assembly-qualified names for type references with Version, Culture, and PublicKeyToken
Fix float32/float64 missing from VisitSimpleType switch
Fix core assembly resolution to match native ilasm: prefer System.Private.CoreLib, then System.Runtime, then mscorlib, then netstandard, with fallback to creating mscorlib reference. Also fix AssemblyRef table emission and dictionary key comparison.
Add tests for ClassLayout, FieldLayout, FieldRVA, and core assembly resolution functionality
