Supports writing complex types to ClickHouse while ensuring no loss of type.

Problem

no

Proposal

Slice and Map are stored using the OTLP/JSON format. However, there isn't a method to directly convert pcommon.Value to OTLP/JSON format. We have to implement it ourselves. The best-case scenario is that the Otel Collector accepts our Feat proposal: open-telemetry/opentelemetry-collector#12826 Otherwise, we will need to perform a lot of duplicated work: #6935 (comment)
