[PoC] Enable Golang dead code elimination

[huww98]

What type of PR is this?

/kind cleanup

What this PR does / why we need it:

Some packages use reflection in a way that prevents Golang linker from eliminating dead code in the binary. We should fix all of them.

• golang.org/x/net/trace renders go template in init()
• github.com/json-iterator/go relies on github.com/modern-go/reflect2. This is used by
  • github.com/alibabacloud-go/tea/tea (aka. Alibaba Cloud OpenAPI SDK v2)
  • github.com/aliyun/alibaba-cloud-sdk-go/sdk (aka. Alibaba Cloud OpenAPI SDK v1)
  • sigs.k8s.io/structured-merge-diff/v4

This PR fixes them by switching to fork version, or modifying the vendor directory directly, just as a PoC. With all of them fixed, the binary size of CSI is shaken from 66M to 31M (47%), impressive!

Binary size tested by

GOOS=linux GOARCH=amd64 go build -ldflags '-s -w' .
du -h ./alibaba-cloud-csi-driver
