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

[jcbhmr]

would be fixed by #49205

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

	%c	ANSI
Node.js	❌	☑️
Deno	☑️	☑️
Bun	☑️	☑️
Chrome	☑️	☑️
Firefox	☑️	❌
Safari	☑️	?

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"
