obj: Move Platform and InitOptions fields into core.windows (#1309)

Browse source 
* obj: Make field tracking use a single bitset

* obj: module: fix comment

* obj: Move `Platform` state and `InitOptions` fields into `core.windows`, initial push, only triangle example working on macos currently

* obj: `get` and `getValue` (renamed `getAll`) now do not return optionals, comment revisions, `device` is no longer optional, `native` is optional

* core: Lots of cleanup of unnecessary comments

* core: `Event`s now all contain `window_id`, darwin/windows: event functions now send window id

* core: comments, examples: fix `core-custom-entrypoint`
