Null[T any] support

[nakagami]

What is Null in go 1.22?

• https://pkg.go.dev/database/sql#Null
• https://pkg.go.dev/database/sql#Null.Scan
• https://pkg.go.dev/database/sql#Null.Value

We will implement this feature.

I think this was introduced in go v1.22, but go v1.20 is the last version supporting W7, so implementing this would difficult development in W7 environments ...
