Delay moving networkState back to Idle until we have retrieved media's
metadata.

The MediaPlayerPrivateWebM currently load the entire file upfront to build
a sample table. This caused the networkState to move to Idle and stop
delaying the load. As such, the intrinsic dimensions of the video element
were incorrect when the test ran.

Fly-by fix: move the networkState to NETWORK_LOADING once we start receiving
buffers from the network as per https://html.spec.whatwg.org/multipage/media.html#concept-media-load-algorithm.

Covered by existing tests.

* LayoutTests/platform/mac-wk2/TestExpectations: Re-enable tests.
