### What?
Extends visibility into what view is being shown so custom components
have context as to where they are being rendered.
**This PR does not add React Context.**
### Why?
This was needed for the multi-tenant plugin where the selector is in the
navigation sidebar and has no way to know if it is being shown inside of
a document or the list view.
I assume other users may also want their server components to be aware
of where a component is rendering before hitting the client. An example
would be wanting to redirect on the server instead of on the client,
this is how multi-tenant redirects users from "global" enabled
collections to the document view.
### How?
Adds 2 new variables that are determined by the view being routed to.
`viewType` - which view is being rendered, ie `list`, `document`,
`version`, `account`, `verify`, `reset`
```ts
type ViewTypes =
| 'account'
| 'dashboard'
| 'document'
| 'list'
| 'reset'
| 'verify'
| 'version'
```
`documentSubViewType` - which tells you what sub view you are on, ie
`api`, `livePreview`, `default`, `versions`
```ts
type DocumentSubViewTypes =
| 'api'
| 'default'
| 'livePreview'
| 'version'
| 'versions'
```
