specify locale-dependent font list for UI on ChromeOS, so that those fonts have higher priority over the fallback fonts Pango picks up.

BUG=103860
TEST=build aura, start chromium in 'ar' locale. type in Arabic and check the Arabic text's shapes. remove IDS_UI_FONT_FAMILY_CROS from 'ar' resource file, build aura again, start chromium in 'ar', type in Arabic and the Arabic text's shapes should be different.
