In Web-Spec, `size` is double but in WebKit's implementation, it was using 'int',
so this PR just changes it to 'double'.

* Source/WebCore/html/track/VTTCue.h: Change 'size' to 'double' and also usage in 'setSize()' argument
* Source/WebCore/html/track/VTTCue.cpp:
(VTTCue::setSize): Update argument to 'double'
* LayoutTests/imported/w3c/web-platform-tests/webvtt/api/VTTCue/size.html: Add Test Case (manually)
* LayoutTests/imported/w3c/web-platform-tests/webvtt/api/VTTCue/size-expected.txt: Add Test Case Expectation
* LayoutTests/imported/w3c/web-platform-tests/html/semantics/embedded-content/media-elements/track/track-element/vtt-cue-float-precision-expected.txt: Rebaselined
* LayoutTests/media/track/track-webvtt-tc019-cue-size.html: Removed in favor of 'WPT' test
* LayoutTests/media/track/track-webvtt-tc019-cue-size-expected.txt: Ditto
