worker: add setEnvironmentData/getEnvironmentData
These APIs allow arbitrary, cloneable JavaScript values to be set and passed to all new Worker instances spawned from the current context. It is similar to `workerData` except that environment data is set independently of the `new Worker()` constructor, and the the value is passed automatically to all new Workers. This is a *partial* fix of #30992 but does not implement a complete fix. Signed-off-by: James M Snell <jasnell@gmail.com>
