Fix "missing resolve surface" issue in RG Compiler logic with MSAA & UnsafePass

Fix https://jira.unity3d.com/browse/UUM-73154

This PR fixes regression introduced by https://github.cds.internal.unity3d.com/unity/unity/pull/46702 where UnsafePass using a MSAA texture would result in "Missing resolve surface" errors. This was because the change was incorrectly always setting `needsResolvedData = true`. This is incorrect in the situation where the unsafe pass is binding it as multisampled texture - in this situation we never resolve (as mentioned by a comment a couple of lines up).
