Add file configuration types for Tracer, Meter, and Logger

Implement ExperimentalTracerConfig, ExperimentalTracerConfigurator,
ExperimentalTracerMatcherAndConfig and their Meter/Logger equivalents
as defined in the declarative configuration spec.

- Add 9 new configuration model headers (Config, MatcherAndConfig,
  Configurator for each signal)
- Wire configurator fields into TracerProviderConfiguration,
  MeterProviderConfiguration, and LoggerProviderConfiguration
- Implement YAML parsing for the new configuration types in
  ConfigurationParser
- Add ScopeConfigurator creation with wildcard name matching in
  SdkBuilder
- Add unit tests for parsing the new configurator sections

Resolves #3915
