fix(cloudflare): Account for static fields in wrapper type

[AbhiPrasad]

fixes #16247

By adjusting the generic, we'll make sure that we don't erase static fields with the instrumentDurableObjectWithSentry function. See an example below:

class MyDurableObjectBase extends DurableObject {
  public static readonly VERSION = '1.0.0';
}

const MyDurableObject = instrumentDurableObjectWithSentry(
  () => ({
    dsn: 'https://example.com/sentry',
    tracesSampleRate: 1.0,
  }),
  MyDurableObjectBase,
);

console.log(MyDurableObject.VERSION); // This will now work correctly

By moving the DurableObjectClass into it's own generic (new (state: DurableObjectState, env: E) => T), which we named C, it helps preserve the exact constructor type of the input class, including all its static properties and methods.

This was previously being lost by not aligning the DurableObjectClass with the function return value.
