Pete Steyert-Woods 091584830b feat(codec/json): add opt-in encoding/json/v2 codec behind jsonv2 tag
As an experiment, with a thought for how Gin might eventually migrate to
and use features from jsonv2, I have put together a new json/codec for
json/v2.

---

Selected with -tags jsonv2, and constrained to go1.27 &&
goexperiment.jsonv2 since encoding/json/v2 is still gated by the
experiment in 1.27 and GOEXPERIMENT=nojsonv2 makes it unimportable.

json.go negates that entire expression, mirroring how it already
negates sonic's OS constraint, so -tags jsonv2 on Go 1.25/1.26 falls
back to encoding/json rather than leaving API nil.

Uses json.DefaultOptionsV1() to keep behaviour identical to the v1
codec: v2's native defaults would render nil slices/maps as []/{} and
match member names case-sensitively, silently zeroing fields that
previously bound.

Fills three v1 gaps v2's API doesn't cover directly: UseNumber has no
exported option, so it's reproduced with a custom *any unmarshaler;
MarshalWrite omits Encoder.Encode's trailing newline; MarshalIndent
becomes jsontext.WithIndentPrefix + WithIndent.
