[localization] Add default temperature unit to the locale (#24059)

# Why

We want to add a temperature unit field which will return the
temperature unit used in the region
ENG-6859

# How

On iOS the unit is based on the current settings in the region tab of
the settings app (note: settings values are ignored in iOS simulator so
any testing in the future should be done on a physical device)
On Android and web a list of regions which use fahrenheit is used and
compared with the current device region.

# Test Plan

Tested in Bare Expo on Android 13, iOS 16 and web
