chore(sec): unify usage of crypto/rand.Read (#7453)

Browse source 
- Unify the usage of [`crypto/rand.Read`](https://pkg.go.dev/crypto/rand#Read) to `util.CryptoRandomBytes`.
- Refactor `util.CryptoRandomBytes` to never return an error. It is documented by Go, https://go.dev/issue/66821, to always succeed. So if we still receive a error or if the returned bytes read is not equal to the expected bytes to be read we panic (just to be on the safe side).
- This simplifies a lot of code to no longer care about error handling.
