Re: [whatwg/webidl] Intent to use BigInt/numeric union in WebNN (Issue #1388)

> Seems like it should be (long long or BigInt) then.

The WebNN user calls a function to apply an operation on a multidimensional tensor (e.g. fill a constant, fill a sequence, pad with a constant value) or to create a multidimensional tensor, where those tensors can be of various data types (including float64/int64/uint64/...), and the caller passes a scalar parameter to that function call which should be able to represent any of the target tensors potential values. Using `BigInt` or `long long` would just introduce the *opposite* problem, as integer types cannot express float64 point precision (3.4 would be truncated to 3).

The current definition @miaobin has prototyped for a constant sequence fill is:

```
MLOperand constant(MLOperandDescriptor desc, (double or bigint) start, (double or bigint) step);
```
