[js/web] revise TensorView (#17473)

### Description

This change:
- removes the unused `Tensor` types declared in
/js/web/lib/wasm/jsep/tensor.ts
- removes duplicated util functions in  /js/web/lib/wasm/jsep/tensor.ts
- renames /js/web/lib/wasm/jsep/**tensor.ts** to
/js/web/lib/wasm/jsep/**tensor-view.ts** and update corresponding
references. It was kind of confusing that we have multiple `Tensor`
types defined in different places also we have multiple `tensor.ts`
source files.

This is one of the prerequisites for supporting IO binding for WebGPU
buffer in onnxruntime-web.
