FR: utilize slices and maps Golang packages for testing helper functions

With the advent of the `slices` and `maps` packages promotion from experimental to core in Go 1.21, and generics in 1.17, we now have e.g. https://pkg.go.dev/slices#Equal. Could we have helper functions as part of the type https://pkg.go.dev/github.com/hashicorp/terraform-plugin-testing/helper/resource#TestCheckFunc that e.g. ascertain `list` and `set` equality instead of using the cumbersome https://pkg.go.dev/github.com/hashicorp/terraform-plugin-testing/helper/resource#example-TestCheckResourceAttr-TypeListAttribute?

There are for sure other examples, but I feel the above is demonstrative of what I am trying to communicate.
