Incompatible with Go 1.23 due to locking down linkname using

[HeRaNO]

Describe the bug

Upstream JSON lib sonic is suffering from linkname usage locking down. And it affects hertz according to reports.

          got the same issue from `cloudwego/hertz`.

Also can find more information at bytedance/sonic#637

BTW, linkname is used in hertz, too. So maybe we need an investigation.

To Reproduce

1. Download Go 1.23 RC1
2. Build a naive Hertz project
3. See errors in building phase

Expected behavior

No error should be presented.

Additional context

We have an update PR (#1106 ) but idle for a time. I can compile a naive hertz project with Go 1.21, and it runs OK. Please consider bumping the PR status.

For the following code:

package main

import (
	"context"

	"github.com/cloudwego/hertz/pkg/app"
	"github.com/cloudwego/hertz/pkg/app/server"
	"github.com/cloudwego/hertz/pkg/common/utils"
	"github.com/cloudwego/hertz/pkg/protocol/consts"
)

func main() {
	h := server.Default(server.WithHostPorts(":12345"))

	h.GET("/ping", func(c context.Context, ctx *app.RequestContext) {
		ctx.JSON(consts.StatusOK, utils.H{"ping": "pong"})
	})

	h.Spin()
}

Compiling with Go 1.23-rc1:

go build -tags stdjson

and the error message is:

In addition, hertz also has linkname used in protobuf codegen. I'm afraid it cannot compile under Go 1.23 even if we bypass sonic issue.

I found that we used sonic https://github.com/cloudwego/hertz/blob/develop/pkg/app/server/binding/internal/decoder/sonic_required.go here, but with a wrong(?) gjson tag. Not sure whether we should change it to stdjson.

@li-jin-gou Hi. The code above cannot be compiled under Go 1.23-rc1. Could you please take a look?
