Proposed resolution

• Perform an exhaustive accessibility review of the current third party JS library (see https://github.com/jackocnr/intl-tel-input/issues for known issues).
• Perform an exhaustive UX evaluation of the third party JS library and gather reasonable default configurations for the 80%.
• Consider offloading international telephone number support to either a sub-module, or external module that can receive dedicated support.
• Only load inline validation javascript when the clientside_validation module is enabled.
