TRUSTX Bid Adapter: initial release (#14218)

* TRUSTX Bidder Adapter

* Remove trustx alias in favor of standalone adapter

Remove trustx alias from grid adapter as a new standalone trustx adapter
is being introduced. Keeping the alias would cause conflicts when both
adapters are present in the same Prebid.js build.

* Update default ttl and usync delete url

* Align docs/tests with param type

* Refactor duplicate code patterns

* refactor & simplify adapter

- Remove localStorage user ID handling (using Prebid User ID modules)
- Remove onDataDeletionRequest (not needed)
- Remove custom keywords processing
- Remove unused utility imports
- Update doc overview

* Fix linter error
