顔が広い is the predicative form (e.g., 彼は顔が広い), while 顔の広い is the attributive form used before nouns (e.g., 顔の広い人). Both share the same meaning.
The expression literally means 'face is wide,' metaphorically suggesting a broad social presence. The exact origin is uncertain, but it likely derives from the idea of one's face being widely recognized.
