Description
This change uses a TypeScript trick to infer global types in onnxruntime-common. Thanks to the strong type system of TypeScript, we are able to refer to types that may not be available in the context.
This helps to keep onnxruntime-common not to include dependencies like "@webgpu/types", and still being able to use the types in the declaration. See comments of
TryGetGlobalType
intype-helper.ts
