This patch ports over the spec defined operation `GetOption` from
JavaScript to C++:
https://tc39.github.io/ecma402/#sec-getoption
The JS implementation will be deleted once all it's
users are migrated.
Refactors LocaleConstructor to use this method which fixes some test262
tests. The test262 test status file is updated to reflect this.
