Support multiple locales for font language settings.
Some fonts support multiple scripts, for example, some fonts for
Korean supports not only "Kore" but also "Jamo".
To select fonts based on their multiple languages, this CL introduces
the following changes:
- Compares all languages of the font family and use the maximum score
for font selection.
- Even if each language of the font family doesn't support the requested
language, the font get score of 2 if the requested font is covered by
all of the languages of the font family. For example, the font for
"ko-Hang,ko-Hani" gets score of 2 for the requested language "ko-Kore".

Introduce multiple language based font fallback.
The motivation of this CL is enhance the font fallback score design
to support multiple language font fallback.
This CL contains following changes:
- Break language based font score into two: script-based score and
primary-language-based score.
- The primary-language-based score is 0 if the script-based score is 0.
If the script-based score is not 0 and the primary language is the
as same as the requested one, the font gets an extra score of 1.
- The language score gets a higher multiplier for languages higher in
the locale list.

Save all kind of script tags into FontLanguage.
This is 2nd attempt of I8df992a6851021903478972601a9a5c9424b100c.
The main purpose of this CL is expanding FontLanguage to be able to
save full script tag. Previously, FontLangauge kept only limited script
tags. With this CL, FontLanguage keeps all script tags.
This CL contains the following changes:
- FontLanguage changes:
-- Moved to private directory not to be instantiated outside of Minikin.
-- Removed bool(), bits(), FontLanguage(uint32_t) methods which are no
longer used.
-- Change the FontLanguage internal data structure.
-- Introduces script match logic.
- FontLanguages changes:
-- Moved to private directory not to be instantiated outside of Minikin.
-- This is now std::vector<FontLanguage>
- FontLanguageListCache changes:
-- Now FontLanguageListCache::getId through
FontStyle::registerLanguageList is the only way to instantiate the
FontLanguage.
-- Normalize input to be BCP47 compliant identifier by ICU.

Introduce FontLanguageListCache.
FontLanguageListCache is an intentionally leaky singleton and its
internal cache won't be purged.
