wasm: Running the go wasm example fails using nodejs

[swaingotnochill]

What version of Go are you using (go version)?

$ go version
go1.20.2 linux/amd64

Does this issue reproduce with the latest release?

What operating system and processor architecture are you using (go env)?

What did you do?

What did you expect to see?

Simple "Hello World"

What did you see instead?

Node.js v19.7.0
exit status 1

PS: I am following this example in the wiki

$ export PATH="$PATH:$(go env GOROOT)/misc/wasm"
$ GOOS=js GOARCH=wasm go run .
Hello, WebAssembly!
$ GOOS=js GOARCH=wasm go test
PASS
ok  	example.org/my/pkg	0.800s

Seems to be an issue with newer versions of node (>=19)

$ node --version
v19.7.0

$ go version
go version go1.20.2 linux/amd64

$ export PATH="$PATH:$(go env GOROOT)/misc/wasm"
$ GOOS=js GOARCH=wasm go run .
...wasm_exec_node.js:25
globalThis.crypto = {
                  ^

TypeError: Cannot set property crypto of #<Object> which has only a getter

Node.js v19.7.0
exit status 1

$nvm use default
Now using node v16.16.0 (npm v8.11.0)

$ GOOS=js GOARCH=wasm go run .
Hello, WebAssembly!

Looks like we got webcrypto on nodejs 19. It conflicts with our own definition of crypto in the wasm exec node:

@seankhliao This is a bug in go and I think the fix should be included in 1.20 (if there is plan for a new hotfix), otherwise wasm on node is broken for versions newer than v19.

Fixed by #56860

Fix was not ported to go 1.20

[seankhliao]

given our support policy of active LTS, I don't see this qualifying for backport.
