message: Export `local_conv1d`/`local_conv2d` in `tf.keras.backend`
  This fix tries to address the issue raised in 25546 where
  there is a mismatch between `tf.keras.backend` and `keras.backend`
  for `local_conv1d`/`local_conv2d`.
  This fix exports `local_conv1d`/`local_conv2d` in `tf.keras.backend`,
  so that `tf.keras.backend` is compatible with `keras.backend`
  (https://keras.io/backend/).
  This fix fixes 25546.
