  Properly Propagate RecoveryExpr through RequiresExpr

Commit 3d7946c58 implemented a DR that allowed us to error in a case
where an ill-formedness in a RequiresExpr is diagnosed as a satisfaction
failure.  However, it failed to cover cases where the RequiresExpr had
Requirements that failed for similar reasons.

This patch propagates the RecoveryExpr "containsErrors" correctly
through RequiresExpr.

Fixes: #61776
