dataconnect(change): refactor toCompactString() for future code reuse

[dconeybe]

This PR refactors data connect's internal logic for calculating debug logging strings, specifically focusing on the conversion of protobuf messages to compact string representations.

Highlights

• Created a new DeserializeUtils utility class to centralize the conversion of protobuf GraphqlError and ListValue objects into internal data structures.
• Refactored ProtoUtil.toStructProto() to leverage DeserializeUtils.
• Enhanced StructProtoBuilder with new helper methods for handling GraphqlResponseExtensions and GraphqlError collections.

Changelog

3 files changed

• CHANGELOG.md: Added a entry for the internal refactor of debug logging strings.
• DeserializeUtils.kt: Introduced this new utility class with methods to convert protobuf messages to internal types.
• ProtoUtil.kt: Refactored toStructProto and updated StructProtoBuilder with more efficient data handling methods.

Code Review

This pull request refactors the calculation of debug logging strings by introducing a new DeserializeUtils utility and cleaning up ProtoUtil. The changes involve moving error deserialization logic and streamlining the construction of protobuf structs for responses. Feedback includes a suggestion to simplify a when block in DeserializeUtils using toCompactString() for better consistency and a recommendation to remove an unused putValue method in ProtoUtil.
