- remove IEquatable Implementation from TypeName and AssemblyNameInfo (and GetHashCode too)
- parser should not enforce runtime-specific rules like illegal type decorators (ByRef to ByRef etc)
- add XML docs for the new AssemblyNameInfo type
- propagate ProcessorArchitecture and ContentType from AssemblyNameInfo to the created AssemblyName
- reject PublicKeyToken of odd length
- remove checked arithmetic for getting node count: it's impossible to parse a name that would cause int overflow
- add test case for escaped closing square bracket in the assembly name
- remove unused code
- address TODOs
- add clarifications for ECMA divergence
- remove one step from AssemblyNameInfo -> AssemblyName -> RuntimeAssemblyName conversion for NativeAOT

- unify syntax for character checks
- remove false statement about unreachable code from the AssemblyNameParser
- fix whitespace formatting
- reduce code duplication and supress RS0030 for TypeSystem (we need to use System.Linq.ImmutableArrayExtensions.ToArray)
- use hungarian notation for static fields
- remove boxing
- pass VSB by reference to avoid resource leaks
- use HexConverter.TryDecodeFromUtf16

- don't throw TypeLoadException in the parser, let loader do that
- add Debug.Assert(typeName.IsSimple) for clarity
- always include invalid character index in the error message
- remove resources added to CoreLib (they are never going to be used)
- use [DoesNotReturn] and implement proper throw helper pattern
- remove outdated comment about name validation
- AssemblyNameInfo.Flags should return the exact value provided in ctor
- don't allocate FullName until it's really needed
- refactor Make and Resovle methods into one method
- fix the test: specify namespace to make sure the type loader loads System.Int32 and later throws TypeLoadException for byref to byref
