Modernize Japanese system font fallback list for Windows

Modernize Japanese system font fallback list for Windows

This patch changes Japanese system font fallback list for Winodws to
prefer more modern, post-ClearType era fonts. This change improves font
rendering of generic font families and system fallback on Windows for
Japanese characters.

This change may trigger hidden issues as these fonts includes internal
leading in their font metrics. Such issues will be tracked separately
as we find them.

"Yu Gothic" is more modern than "Meiryo" and is the default font for
Win10. However, its rendering, especially in Blink, is still suboptimal
that this patch puts "Meiryo" higher than it.

The font lists for katakanaOrHiragana, katakana, and hiragara are
merged as ditiguishing them is not necessary.

Also in order to ensure rebaselined images look sensible, added
lang="ja" to tests with Japanese characters.

Results for Win10 failures where this change affects are reviewed and
removed Failure expectations, except track-cue-rendering-vertical.html
that look to need more investigations.

PTAL.

Not sure how well this would work, but I think it's worth a try, when we have
the maximum time of Canary.

Looking into changes for Chinese as well.

LGTM
