The diff rendering logic tests whether the DetailedDiff is nil to determine whether to use it for rendering or defer to older older supported approaches to computing diffs.
The new logic added in https://github.com/pulumi/pulumi/pull/7226 could lead to replacing a nil DetailedDiff with an empty DetailedDiff, whcih would make the rendering logic believe that a DetailedDiff was present but empty, instead of missing entirely.
This change ensures that we maintain nil-ness of the DetailedDiff when we transform it for handling of replaceOnChanges.
Also adds tests for this and other cases on applyReplaceOnChanges.
Fixes#7486.

* Fix the nullability of config type properties in C# codegen (#4379)
These changes add support for passing `ignoreChanges` paths to resource
providers. This is intended to accommodate providers that perform diffs
between resource inputs and resource state (e.g. all Terraform-based
providers, the k8s provider when using API server dry-runs). These paths
are specified using the same syntax as the paths used in detailed diffs.
In addition to passing these paths to providers, the existing support
for `ignoreChanges` in inputs has been extended to accept paths rather
than top-level keys. It is an error to specify a path that is missing
one or more component in the old or new inputs.
Fixes#2936, #2663.
