Additional configuration for Url, Ip and Email fields

[emteknetnz]

Work done in #11403 add support for FieldValidators, such as UrlFieldValidator and IpFieldValidator as well some new corresponding fields such as DBUrl, DBIp and DBEmail

These new fields validators could benefit from having some additional configuration options:

• UrlFieldValidator could benefit from being able to specify allowable schemes e.g. ['http', 'https', 'ftp']
• IpFieldValidator could benefit from being able to specify the symfony constraint to use e.g. Ip:V4, Ip:V6
• EmailFieldValidator could benefit from being able to specify symfony Email validation mode

Acceptance criteria

• Developers are able to specify the allowable URL scheme in private static $db e.g. 'MyURL' => 'URL(50, ("http", 'https", "ftp"))' or whatever format makes sense
• The same can be done with IP e.g. "'MyIP' => 'IP(32, v4)', or whatever makes sense
• The same can be done with Email e.g. "MyEmail => 'Email(64, strict)', or whatever makes sense
• DBField FieldValidation matches what is specified in the DB schema
• FormFields are autoscaffoled with the FieldValidation that matches
• UrlField::validate() is updated to use UrlFieldValidator
