ART: Add cutout for Unsafe.putObjectVolatile
Add an unstarted-runtime cutout for putObjectVolatile.
Allows to compile-time initialize:
* android.content.res.Configuration
* android.icu.text.PluralRules$SimpleTokenizer
* android.icu.text.UnicodeSet
* android.icu.util.VersionInfo
* android.util.LocaleList
May allow follow-up changes to compile-time initialize
more ICU classes.
