webnn: Support scatterElements in tflite converter

There is no TFLite operator to map directly WebNN scatterElements, but
it can be supported with tfl.scatter_nd as the test cases[1] and the
doc[2] described.

The indices also need to be converted like gatherElements.
The update operand must be reshaped to one dimension[3].
