Dominic Farolino 9ecde94e2a Bug 2042248 [wpt PR 60158] - WebMCP: Expose document.modelContext, a=testonly
Automatic update from web-platform-tests
WebMCP: Expose document.modelContext

Per https://github.com/webmachinelearning/webmcp/issues/173 and
https://github.com/w3ctag/design-reviews/issues/1231#issuecomment-4502765330,
we're moving `modelContext` to `document` from `navigator`. This CL does
that, but keeps `navigator` exposure around for a bit and dispatches a
console warning when it is used.

This CL also updates all web platform tests to use
`document.modelContext`. There might be other lingering tests elsewhere,
but we can update those when we fully remove the API.
