Stabilize scope configuration ({Signal}Config, {Signal}Configurator)

Stabilize

• TracerConfigurator
• MeterConfigurator
• LoggerConfigurator

The original PR was this: #3877

These configurators are used to suppress signal telemetry according to the InstrumentationScope

These configurators have been implemented in multiple language projects:

• In Java. See: Scope config opentelemetry-java#6375
• In C++. See:
  • [SDK] Add tracer scope configurator opentelemetry-cpp#3137
  • [SDK] Add meter scope configurator opentelemetry-cpp#3268
  • [SDK] Add logger scope configurator opentelemetry-cpp#3282
• In PHP. See:
  • implement scope configuration opentelemetry-php#1353

The reason

Projects outside OpenTelemetry need the functionality and they are accessing it with workarounds and with no guarantees of continuity.
Example: open-telemetry/opentelemetry-java#7312

I didn't realize that php and c++ had implemented this. Cool!

That means this feature meets the prototype requirement for stabilization. Curious if anyone has encountered any feedback that would cause us to reconsider the design.
