EventSource source generator should mark both source and IL as autogenerated

[danmoseley]

Per #64541, it should emit <autogenerated> into the source and also [GeneratedCodeAttribute...] for the IL.

Our other generators do this; this enables tooling and servicing scenarios.

eg regex generator

runtime/src/libraries/System.Text.RegularExpressions/gen/RegexGenerator.Emitter.cs

Lines 27 to 31 in 9df2832

	private static readonly string s_generatedCodeAttribute = $"[global::System.CodeDom.Compiler.GeneratedCodeAttribute(\"{typeof(RegexGenerator).Assembly.GetName().Name}\", \"{typeof(RegexGenerator).Assembly.GetName().Version}\")]";
	/// <summary>Header comments and usings to include at the top of every generated file.</summary>
	private static readonly string[] s_headers = new string[]
	{
	"// <auto-generated/>",
