feat(core): rename ProbabilitySampler to TraceIdRatioBasedSampler

[legendecas]

TraceIdRatioBasedSampler are determinist samplers based on trace ids.

Which problem is this PR solving?

• Fixes: Rename ProbabilitySampler to TraceIdRatioBasedSampler and implement ratio sampling #1487

Short description of the changes

• rename ProbabilitySampler to TraceIdRatioBasedSampler
• TraceIdRatioBasedSampler samples span based on trace ids deterministically. A TraceIdRatioBased sampler with a given sampling rate also sample all traces that any TraceIdRatioBased sampler with a lower sampling rate would sample.

Note: per the time the PR is filed, the implementation detail of the sampler regarding the trace ids on spec is not yet determined. Though there will be no API changes regarding the new spec on this part, so it is safe to land the API with this primitive reminder based implemention.

This is a breaking change.
