adds support for Uint8ClampedArray

[prathikr]

Fixes #21753

[fs-eire]

also need to add type declaration for uint8 in common\lib\tensor.ts

[fs-eire]

can also add one test in js/common/unit-test/tensor/constructor-type.ts for:

[uint8] new Tensor(uint8ClampedArray, dims): uint8 tensor can be constructed from Uint8ClampedArray
[uint8] new Tensor('uint8', uint8ClampedArray, dims): uint8 tensor can be constructed from Uint8ClampedArray

[fs-eire]

seems still need code formatting

[fs-eire]

To precisely explain the requirement of "support ClamppedUint8Array", it means "to allow creating uint8 tensors from ClamppedUint8Array". It does not change the underlying storage of a uint8 tensor (it is always Uint8Array). To break down, the work items are:

• update TypeScript API to add new Tensor(data: ClamppedUint8Array, dims?: readonly number[])
• update TypeScript API to add new Tensor(type: 'uint8', data: ClamppedUint8Array, dims?: readonly number[])
• update actual implementation to enable the 2 interfaces mentioned above
• add TypeScript typecheck and constructor unittest

Allowing users to create a uint8 tensor from both Uint8Array and ClamppedUint8Array does not mean there should be 2 different types ('uint8' and 'uint8c'). Tensor types are logically mapping to ONNX Tensor data type, and there is no point to introduce 2 types for uint8.

@fs-eire I reverted the change to previous solution which has Uint8ClampedArray implemented as a uint8 datatype. However, I cannot seem to find a way to do this without including uint8: Uint8Array | Uint8ClampedArray; in DataTypeMap which you previously mentioned will affect type inferencing.

Please advise on if this is ok or what I can do differently. The current code passes the tests I've set up.

[fs-eire]

test is failed.
