Revert "Explicit ImageList ownership management. (dotnet#3601)" This reverts commit 03db3fb. Revert "Fix `ListView` no longer displays images (dotnet#4184)" This reverts commit d0608e7. We have observed an instability of tests under stress (and reasonably high degree of concurrency) presumably caused by ImageList lifetime handling (notably dotnet#3358). The changes introduced in dotnet#3601 have helped with tests stability, however resulted in a number of regressions, such as dotnet#4169 and dotnet#4275. Restore the original implementation given it worked reasonably well for the past so many years. (cherry picked from commit b0ee5da)

Customer Impact
ImageListbehaviours should be the same as in .NET Framework and .NET Core.Regression?
