[ASTImporter] Remove duplicated and dead CXXNamedCastExpr handling code.

Summary:
`CXXNamedCastExpr` importing is already handled in the respective `VisitCXXNamedCastExpr` method.
So this code here can never be reached under normal circumstances and we might as well remove it.

This patch shouldn't change any observable behavior of the ASTImporter.
