Check for existence of column before running for more validators.

[jcpitre]

Describe the problem

In PR https://github.com/MobilityData/gtfs-validator/pull/1875 we added logic so we don't have to call some validators if the columns related to the validator do not exist.

This was implement for some validators, but not all. We should add this check to all validators that would benefit.

This was implemented in #1875

• For generated validators:
  • Mixed case validators will not be run if the column that is annotated with MixedCase is not present
  • Foreign key validators will not be run if the column containing the foreign key is not present
• Custom validators:
  • StopTimesGeographyIdPresenceValidator will not be run in none of stop_is, location_id and location_group_id is present
  • AttributionWithoutRoleValidator will not be run if none of isProducer, isOperator and isAuthority columns are present
  • StopNameValidator validator will not be run if none of stopName and locationType is present

You can find a list of all validators here.
