`console.log`: Improve ArrayBuffer/TypedArray output formatting (Option 2)

[pkalsi97]

Feature Description

Improve console.log output formatting for ArrayBuffer and TypedArray by modifying the traverseValue function to avoid json.Marshal entirely.

Suggested Solution (optional)

Following the discussion in #5469, two options were explored to achieve Deno-style output for ArrayBuffer and TypedArray:

• Option 1 (implemented in #5480): Uses json.Encoder with SetEscapeHTML(false). This prevents <> → \u003c\u003e escaping but retains extra quotes around formatted strings for nested objects.

{ "b": "ArrayBuffer { [Uint8Contents]: <00 00 00 00 00 00 00 00>, byteLength: 8 }", "v": "Int32Array(2) [ 4, 2 ]" }

• Option 2 (this issue): Modifies traverseValue to avoid json.Marshal entirely, achieving:
  • No HTML escaping (<> stays as <>)
  • No extra quotes around formatted strings
  • Output style: { key: value } for objects and [ elem, elem ] for arrays
  • Fully matches Deno-style output

{ b: ArrayBuffer { [Uint8Contents]: <00 00 00 00 00 00 00 00>, byteLength: 8 }, v: Int32Array(2) [ 4, 2 ] }
