Port Golang select3.go Test

[shota-tsuji]

Port of the select3.go test.

Part of #201

Some tests are omitted:

• Empty select statements (they cause a compile error)
• Receiving with the ok flag
• Panic on select send to a closed channel (it blocks instead)

Thanks! Could you resolve CI failures?

As for Miri errors, I think it can be fixed by avoiding leak checks as follows.
