[PATCH v3] dwrite: Prefer Windows platform names regardless of record order.

[Akihiro Sagawa]

In v3,
  - keep existing loop to reflect Nikolay's comment.
    Nikolay, thanks for reviewing.
  - introduce NOT_AVAILABLE constatnt.
IPA Mincho font file is available from
https://ipafont.ipa.go.jp/old/ipafont/IPAMTTC00303.php .

Otherwise localized family name of IPA font isn't available in DirectWrite.
While Wine enumerates localized name in GDI.

N.B. IPA font family (e.g. IPA Mincho) is a bit tricky. It has Japanese
(Kanji) name for Japanese Windows, though it has English (ASCII) name for
Japanese Macintosh. And due to record order, Wine's DirectWrite chooses
Macintosh one.
