Deprecate various columns in the Transit Database Mart Tables

[evansiroky]

Describe the bug

Some columns are not named as "deprecated" when they should be. They are as follows:

Table	Column	Alternative Use
dim_organizations	roles	No longer maintained
dim_organizations	itp_id	An artifact from previous iterations
dim_organizations	caltrans_district	Caltrans Districts are maintained in the "County Geographies" table. To get the Caltrans District for an organization you'd join with bridge_organizations_x_headquarters_county_geography and also dim_county_geography.
dim_organizations	reporting category	This used to be used to calculate which agencies appeared in our default list. This was changed to a different formula in #2675.
dim_organizations	gtfs_static_status	This complex Airtable formula uses outdated info from the services table. See the GTFS Schedule Adoption question for example query.
dim_organizations	gtfs_realtime_status	This complex Airtable formula uses outdated info from the services table. See the GTFS-RT Coverage dashboard instead for example queries to calculate.
dim_services	service_type	The service type has been split up into multiple areas. There is now the dim_services.fixed_route column and paratransit data is pending update work in #3431.
dim_services	mode	Mode information is available via the bridge_services_x_modes table to the dim_modes table.
dim_services	operating counties	Operating County info is available from the bridge_services_x_operating_county_geographies table.
dim_services	gtfs_schedule_status	No longer maintained.
dim_services	gtfs_schedule_quality	No longer maintained.
dim_gtfs_service_data	category	This field has been deprecated in favor of the field "Customer Facing" and a combo of gtfs_datasets.regional_feed_type.
