[APM] Replace ES Archive with synthtrace

[sorenlouv]

We should convert all API tests from ES Archive to Synthtrace. The following tests still rely on archives:

• x-pack/test/apm_api_integration/tests/alerts/chart_preview.spec.ts
• x-pack/test/apm_api_integration/tests/historical_data/has_data.spec.ts
• x-pack/test/apm_api_integration/tests/inspect/inspect.spec.ts
• x-pack/test/apm_api_integration/tests/service_maps/service_maps.spec.ts
• x-pack/test/apm_api_integration/tests/service_overview/instance_details.spec.ts
• x-pack/test/apm_api_integration/tests/service_overview/instances_detailed_statistics.spec.ts
• x-pack/test/apm_api_integration/tests/service_overview/instances_main_statistics.spec.ts
• x-pack/test/apm_api_integration/tests/service_overview/dependencies/index.spec.ts
• x-pack/test/apm_api_integration/tests/services/agent.spec.ts
• x-pack/test/apm_api_integration/tests/services/archive_services_detailed_statistics.spec.ts
• x-pack/test/apm_api_integration/tests/services/top_services.spec.ts
• x-pack/test/apm_api_integration/tests/services/transaction_types.spec.ts

• x-pack/test/apm_api_integration/tests/settings/custom_link.spec.ts
• x-pack/test/apm_api_integration/tests/settings/agent_configuration/agent_configuration.spec.ts
• x-pack/test/apm_api_integration/tests/traces/top_traces.spec.ts
• x-pack/test/apm_api_integration/tests/transactions/breakdown.spec.ts
