Add basic tests for proposal-intl-locale-info (#2987)

* Add basic tests for weekInfo

* Add basic tests for textInfo

* Add basic tests for timeZones

* Add basic tests for numberingSystems

* Add basic tests for hourCycles

* Add basic tests for collations

* Add basic tests for calendars

* Add feature for Intl.Locale-info

* add validation to branding tests for locale-info

Add additional assertion to branding tests for proposal-intl-locale-info
to make sure they don't pass spuriously when the proposal is not
implemented.
