hcp.v2.TelemetryState resource and controller implementation (#20257)

* pbhcp: add TelemetryState resource

* agent/hcp: add GetObservabilitySecrets to client

* internal/hcp: add TelemetryState controller logic

* hcp/telemetry-state: added config options for hcp sdk and debug key to skip deletion during reconcile

* pbhcp: update proto documentation

* hcp: address PR feedback, additional validations and code cleanup

* internal/hcp: fix type sig change in test

* update testdata/v2-resource-dependencies
