Consider adding Tuple* known value checks

Proposal

Now that dynamic type support is in plugin framework, it's possible that provider developers will test dynamic data that could be a tuple. For readability, we should introduce equivalent TupleExact, TuplePartial, and TupleSize known value checks.

Workaround

Currently, you can test this with the List* equivalents, since no restriction is applied for knownvalue checks to be all the same type. Example with ListExact:

func TestDynamicSchemaResource_DynamicAttribute(t *testing.T) {
    resource.UnitTest(t, resource.TestCase{
        ProtoV5ProviderFactories: map[string]func() (tfprotov5.ProviderServer, error){
            "framework": providerserver.NewProtocol5WithError(New()),
        },
        Steps: []resource.TestStep{
            {
                Config: `resource "framework_dynamic_schema" "test" {
                    dynamic_attribute = [true, 1234.5]
                }`,
                ConfigStateChecks: []statecheck.StateCheck{
                    statecheck.ExpectKnownValue("framework_dynamic_schema.test", tfjsonpath.New("dynamic_attribute"),
                        knownvalue.ListExact(
                            []knownvalue.Check{
                                knownvalue.Bool(true),
                                knownvalue.NumberExact(big.NewFloat(1234.5)),
                            },
                        ),
                    ),
                },
            },
        },
    })
}
