2bc46ae8 - [clang] Format "array is too large" diagnostics with separators (#160260)

[clang] Format "array is too large" diagnostics with separators (#160260) We only display this diagnostic with large numbers, so add the separators. Not sure if `295'147'905'179'352'825'841` is much better than `295147905179352825841` but I think it would be nice to have separators in more diagnostics.
