Background and motivation

Console.Write and Console.WriteLine have a bunch of overloads for writing out various data types, but none for ReadOnlySpan<char>. We should add some purely for convenience. You can achieve the same by .ToString()'ing them or by using Console.Out.Write* instead, but it's just a little bit of unnecessary friction.

(I thought we already had an issue for this, but can't find it now.)

API Proposal

namespace System;

public static class Console
{
+   public static void Write(ReadOnlySpan<char> value);
+   public static void WriteLine(ReadOnlySpan<char> value);
}

API Usage

ReadOnlySpan<char> value = ...;
Console.WriteLine(value);
