Reviewed by Eric Carlson.

This patch aligns WebKit with Gecko / Firefox and Blink / Chromium.

Merge: https://src.chromium.org/viewvc/blink?view=revision&revision=189185

Previously 'metadata' tracks were being configured using the "perform
automatic text track selection" algorithm from the the spec, while it
should only have applied step 4 of the "honor user preferences for
automatic text track selection" algorithm.

* Source/WebCore/html/HTMLMediaElement.cpp:
(HTMLMediaElement::configureMetadataTextTrackGroup): function to handle 'metadata' as per spec
(HTMLMediaElement::configureTextTrackGroup): for 'metadatatracks' use new function
* Source/WebCore/html/HTMLMediaElement.h: Add definition for new function
* LayoutTests/imported/w3c/web-platform-tests/html/semantics/embedded-content/media-elements/track/track-element/track-selection-metadata-expected.txt: Rebaselined
