WL#15199: PERFORMANCE_SCHEMA, OTEL METRICS INTERFACE

Description:
-----------
This WL implements core part of the server telemetry metrics feature
with the following deliverables:
* Definition of service to instrument metrics (pfs_metrics_v1)
* Implementation of pfs_metrics_v1 in the performance schema
* Added setup_meter and setup_metrics performance schema tables
* Code base instrumentation using pfs_metrics_v1 to expose metrics:
  - from status variables in core server
  - from status variables in innodb storage engine
  - from status variables in X plugin
  - custom metrics from health monitor component
* Service definition for metric exporter (mysql_server_telemetry_metrics_v1)
* Implementation of this interface in a server component
* A test component (test_server_telemetry_metrics) using the service
  to test the feature
