WL#15201: PERFORMANCE_SCHEMA, OTEL INTERFACE: LOG

Description:
-----------
This WL implements core part of the server telemetry logging feature
with the following deliverables:
* Service definition for log exporter: mysql_server_telemetry_logs
* Implementation of mysql_server_telemetry_logs in performance schema
* Added setup_loggers performance schema table
* Service definition for log clients: mysql_server_telemetry_logs_client
* Implementation of mysql_server_telemetry_logs_client in performance schema
* C++ wrappers for client API to simplify log instrumentation
* Instrument MySQL error logging code to also emit telemetry log records
* Test components (test_server_telemetry_logs_{export,client}) using
  services to test the feature
