Add console.log() %c support for parity with browsers, Deno, and Bun

would be fixed by https://github.com/nodejs/node/pull/49205

My attempt at a compat table of ANSI and %c:

Why this would be a good idea:

• Feature parity with other desktop JavaScript runtimes like Deno and Bun
• Allow documentation authors to recommend using %c instead of ANSI for more compatibility without "%c works everywhere except Node.js" clauses
• %c is ignored in unsupported environments (like current Node.js) whereas ANSI causes jargon to be printed (particularly in Firefox). Thus, encouraging %c is more "progressive enhancement" or "graceful degradation" than ANSI ??

basically just "everyone else is doing it, so it's probably a good idea to conform to what users expect"

プルリクエスト #49205 と前の issue #29605 から始め、そこで特定されている console.log のフォーマット処理のエントリーポイントまたはテストを確認してください。Node.js が、この issue に記載された動作に従って console.log() の %c フォーマットを一貫してサポートすれば完了です。
