### Description
when DOM API is not avaiable, using OffscreenCanvas
### Motivation and Context
In some environment like service worker or web worker, the DOM API is
not avaiable, we can use OffscreenCanvas API to replace
`document.createElement('canvas')`.
Most of the APIs of OffscreenCanvas and HTMLCanvasElement are the same,
except that `toDataUrl` is missing.
It fix this issues #19032
### Description
<!-- Describe your changes. -->
refactor tensor type in onnxruntime-common.
### Motivation and Context
There major motivation is that I am doing a local change to address the
API part of #15312. And I am doing a refactoring of onnxruntime-common
anyway (#15772).
The `tensor.ts` and `tensor-impl.ts` are too large, so I split contents
into multiple files to make the type declarations clearer.
The original target of this change is for API only ( ie. do not refactor
any implementation.). However, there are a few type/implementation
inconsistencies so I also made minimal changes to fix them.
### Changes
- extract `TensorUtils` for non-template interfaces
- extract `TensorFactory` for all overloads of `Tensor.fromImage()`
- refactor options type that used for `Tensor.fromImage()`
- fix JSDoc comments to make option descriptions consistent with actual
type declarations
- fix an inconsistency for `options.format` and `options.bitmapFormat`;
change all `bitmapFormat` to `format`
- extract `ConversionUtils` for `tensor.toDataURL()` and
`tensor.toImageData()`
- put implementations into multiple files from `tensor-impl.ts`
- fix a bug that cause unittest fail. put comments for future fix.
