[SDK] Add tracer scope configurator

[psx95]

Re #2641

Adds scope configurator for Tracers.

Changes

• Updates the Trace SDK to add support for TracerConfigurator as per the spec changes.
• Adds a TracerConfig class that can be used to configure a tracer's behavior as per spec.

Some optional, good-to-have convenience functions were recommended by the spec to accommodate common use-cases - these have not been added in this PR.

See the TracerConfigurator spec for these recommendations. They should be added in a future PR.

For significant contributions please make sure you have completed the following items:

• [X] CHANGELOG.md updated for non-trivial changes
• [X] Unit tests have been added
• [ ] Changes in public API reviewed
