[Feature Request] Built-in Phone Validation

[hongkongkiwi]

Please add an additional validation for phone numbers. This is a pretty common need especially with SMS 2FA, I think this is useful to setup so we can have a @phone

E.164 phone number (used for Phone/SMS etc)

/**
 * Validates a string field value is a valid E.164 phone number format (+[country code][number])
 */
attribute @phone(_ message: String?) @@@targetField([StringField]) @@@validation @@@supportTypeDef

I'm currently using it with a regex, but I think it's worth having it built-in:

  /// The phone number in E.164 format (e.g., +16175551212)
  phone String? @regex('^\\+[1-9]\\d{1,14}$', message: "Phone number must be in E.164 format (e.g., +16175551212)")

No this is not a duplicate. That is related and links to zod E.164 phone number validation. Which actually seems to have been already added in Zod: https://github.com/colinhacks/zod/pull/3476 as a merged PR back in May.

This issue is for adding @phone (or similar) in zenstack to use this functionality.
