Migrated from IdentityModel/IdentityModel#574

Some OAuth 2.0 servers and the OAuth 2.1 draft specification require PKCE, but IdentityModel lacks a method to derive an S256 code challenge from a code verifier, so I have to manually write

var codeChallenge = Base64Url.Encode(SHA256.HashData(Encoding.UTF8.GetBytes(codeVerifier)));

which is not very convenient.
