Add ConstructorBuilder implementation, integrate TypeBuilder.GetXyz() static methods

[buyaa-n]

Constributes to #92975

• Add ConstructorBuilder implementation
• Add DefineConstructorCore and DefineDefaultConstructorCore protected members for TypeBuilderImpl
• Integrate TypeBuilder.GetConstructor(...), TypeBuilder.GetMethod(...) and TypeBuilder.GetField(...) static methods so that they could be used for the new Reflection.Emit.TypeBuilderImpl
• Fix/implement other APIs that needed for accessing/writing types and methods constructed from runtime type and TypeBuilderImpl type (instances of *BuilderInstantiation types, like MethodBuilderInstantiation)
• Populate type and its members tokens on CreateTypeInfoCore(). Refactor Assembly.Save IL emit logic to require referenced types to be created ("baked").

Some misc feedback but otherwise LGTM.

[steveharter]

InvalidOperationException instead?

[buyaa-n]

Followed exception type and message for similar cases

runtime/src/coreclr/System.Private.CoreLib/src/System/Reflection/Emit/RuntimeModuleBuilder.cs

Lines 1142 to 1145 in 9f6ac8c

	if (!arrayClass.IsArray)
	{
	throw new ArgumentException(SR.Argument_HasToBeArrayClass);
	}

[steveharter]

When is the element null in this case?

[buyaa-n]

When the parameters created with parameterTypes array:

runtime/src/libraries/System.Reflection.Emit/src/System/Reflection/Emit/MethodBuilderImpl.cs

Lines 53 to 60 in ffd43b6

	if (parameterTypes != null)
	{
	_parameterTypes = new Type[parameterTypes.Length];
	_parameterBuilders = new ParameterBuilderImpl[parameterTypes.Length + 1]; // parameter 0 reserved for return type
	for (int i = 0; i < parameterTypes.Length; i++)
	{
	ArgumentNullException.ThrowIfNull(_parameterTypes[i] = parameterTypes[i], nameof(parameterTypes));
	}

but not explicitly defined with DefineParameterCore(...)
