Part of https://github.com/open-telemetry/opentelemetry-go/issues/5249 This makes all existing types designed to implement the public Exemplar API public by moving most of `internal/exemplar` to `exemplar`. The only types that are not being made public are `exemplar.Drop`, and `exemplar.FilteredReservoir`. Those types are moved to `internal/aggregate`, and are renamed to `DropReservoir` and `FilteredExemplarReservoir`. The following types are made public: * `exemplar.Exemplar` * `exemplar.Filter` * `exemplar.SampledFilter` * `exemplar.AlwaysOnFilter` * `exemplar.HistogramReservoir` * `exemplar.FixedSizeReservoir` * `exemplar.Reservoir` * `exemplar.Value` * `exemplar.ValueType`
