Description
错误描述：
在 #73194 显式抛出 bigtensor 错误后，
conv_transpose测试时仍旧报 CUDA error 9:问题定位：
检查发现
CUDNN_ENFORCE_TENSOR_SIZE_SUPPORTEDcheck 的位置过于靠后，CUDNN 描述符ConvArgs在构造时就发生错误；因此将前反向的 check 均提前至GPUDNNDataLayout之前修改后，测试通过（已由
paddle_error_dismiss放行）：其他：
conv未发现此问题，但是 bigtensor 测试配置存在 [numpy error]、错误形状等情况，需要在 APITest 中修复conv、conv_transpose的全量回测Pcard-85711
