prelu steps should validate the data type of slope is equal to the data type of input #660

The spec algorithms for most operators check that the input data type is some given type before checking that other parameters use the same data type. See e.g. matmul:

If a’s dataType is not "float32" or "float16", then throw a TypeError. If b’s dataType is not equal to a’s dataType, then throw a TypeError.

prelu doesn't have the latter step, which seems like a bug in the spec?
