Anders Eknert db035b09fc Add support for Go 1.27 & jsonv2 (#8947) ...

Makes OPA build and pass its tests on Go 1.27, while keeping Go 1.25 and
1.26 working. JSON output is unchanged on every supported version.

Go 1.27 json package honours `encoding.TextAppender`. Many v1 ast types
implement AppendText to build their Rego string cheaply, so on 1.27 they
would have marshalled as Rego text. Files built only with 1.27 now
implement MarshalJSONTo.

Library users should keep using `json.Marshal` etc. The MarshalJSONTo
methods are implementation details, are absent from 1.25 and 1.26
builds, and may change.
