Wire the existing ottlexemplar context into metric statement parsing and execution so transformprocessor can mutate exemplar fields on gauge, sum, histogram, and exponential histogram datapoints. Expose default and custom exemplar function hooks alongside metric and datapoint functions, and validate context: exemplar in transform configs. Tests: - go test ./... (from processor/transformprocessor)
