Fix class_info.to_list()

[pswaminathan]

The first commit addresses a crash. On master, with Bazel 4.2.2 (I'm not sure if this was a change stemming from Bazel 4):

$ bazel build //...

This PR also changes the import path for kt_jvm_library to remove the debug messages from rules_kotlin. LMK if you'd rather have that in a separate PR—happy to split it out.

Thanks for the PR! This looks good to me. I would appreciate if the PR is split for the Kotlin import change.

The to_list() change was made to support Bazel 5.0 changes. Reference: bazelbuild/bazel#12780

Probably we need a compat version that support both versions like done on rules_android.

def _list_or_depset_to_list(list_or_depset):
    if type(list_or_depset) == "list":
        return list_or_depset
    elif type(list_or_depset) == "depset":
        return list_or_depset.to_list()
    else:
        return _error("Expected a list or a depset. Got %s" % type(list_or_depset))

Ah, wonderful. Submitted as #11 and #12.
