Add non-throwing version of unpackProperties

Some projects (e.g., bmcweb) don't use functions which throw exceptions.
This change introduces unpackPropertiesNoThrow() function, which returns
optional string. In case of mismatched type or missing property, it will
contain its name. In case of no errors, std::nullopt will be returned.

As a side change, message returned by UnpackPropertyError::what() now
also includes propertyName and reason.

Testing done:
- Added unit tests for unpackPropertiesNoThrow().
- unpackProperties() functionality remained the same.
