Remove declaration of unimplemented methods in LocaleICU

https://bugs.webkit.org/show_bug.cgi?id=154482

Patch by Olivier Blin <olivier.blin@softathome.com> on 2016-02-20
Reviewed by Michael Catanzaro.

detectSignAndGetDigitRange() and matchedDecimalSymbolIndex() are
implemented in PlatformLocale, not LocaleICU.

They were moved out from LocaleICU to NumberLocalizer in r124459
(2012), which has then been renamed as Localizer, then Locale, and
finally PlatformLocale.
