Use agent token for service/check deregistration during anti-entropy (#16097) Use only the agent token for deregistration during anti-entropy The previous behavior had the agent attempt to use the "service" token (i.e. from the `token` field in a service definition file), and if that was not set then it would use the agent token. The previous behavior was problematic because, if the service token had been deleted, the deregistration request would fail. The agent would retry the deregistration during each anti-entropy sync, and the situation would never resolve. The new behavior is to only/always use the agent token for service and check deregistration during anti-entropy. This approach is: * Simpler: No fallback logic to try different tokens * Faster (slightly): No time spent attempting the service token * Correct: The agent token is able to deregister services on that agent's node, because: * node:write permissions allow deregistration of services/checks on that node. * The agent token must have node:write permission, or else the agent is not be able to (de)register itself into the catalog Co-authored-by: Vesa Hagström <weeezes@gmail.com>

```release-note:bug-fix
agent: Only use the `agent` token for internal deregistration of checks and services during anti-entropy syncing. The service token specified in the `token` field of the check or service definition is no longer used for deregistration. This fixes an issue where the agent failed to ever deregister a service or check if the service token was deleted.
