Visual indicator of where fields are used

In order to comply with the [Graylog Information Model Schema](https://schema.graylog.org/en/stable/) (GIM), a lot of work needs to be done on existing setups in order to identify provenance and uses of existing fields, and rename them according to GIM. The purpose of this feature request is to make field management easier via the Graylog UI, by providing a visual indicator that shows where fields are being used across :

- Inputs
- Extractors
- Pipeline rules
- Streams

Similar to https://github.com/Graylog2/graylog2-server/pull/11474 but for fields
