Tuples with elements of different types can be converted to homogeneous
collections (sets or lists), so long as their elements are unifiable.
For example:
list("a", "b") // all elements have the same type
list("a", 5) // "a" and 5 can be unified to string
list("a", 5, null) // null is a valid value for string
However, tuples with elements which are not unifiable cannot be
converted to homogeneous collections:
list(["a"], "b") // no common type for list(string) and string
This commit fixes a panic for this failure case, when the tuple contains
both non-unifiable types and a null value:
list(["a"], "b", null) // should not panic
The null value was causing the unification process to result in a list
or set of dynamic type, which causes the conversion functions to pass
through the original value. This meant that in the final conversion
step, we would attempt to construct a list or set of different values,
which panics.
This tests whether a value contains any unknown values of unknown type. This is different than just testing if any of the nested types are DynamicPseudoType, because a null value of DynamicPseudoType has a different meaning than an unknown value of DynamicPseudoType: the null value's type can't become any more "known".

This PR updates this repo for parity with zclconf/go-cty v1.5.0. The changes remain "Unreleased" with no new release tag for the moment. This prevents a flood of Dependabot PRs like hashicorp/terraform-plugin-testing#444 for all affected providers.
