`SizeAtLeast`, `SizeBetween` and `SizeAtMost` for `knownvalue`

An example:

```go
{
ConfigStateChecks: []statecheck.StateCheck{
statecheck.ExpectKnownValue(
resourceName,
tfjsonpath.New("some_attr"),
knownvalue.SetSizeAtMost(3),
),
statecheck.ExpectKnownValue(
resourceName,
tfjsonpath.New("some_attr"),
knownvalue.SetSizeAtLeast(1),
),
statecheck.ExpectKnownValue(
resourceName,
tfjsonpath.New("some_attr"),
knownvalue.SetSizeBetween(1, 3),
),
},
}
```

There is only `SetSizeExact` today. Similar stuff can be applied to List and Map. I can put up a PR if you guys can confirm this feature is needed.
