Hold a reference to the child widgets in case there are destroyed externally from FlView. If destroyed, drop any frames.

Fixes #192873

Code Review

This pull request prevents crashes when presenting layers on a destroyed or disposed FlView or its renderers. It introduces a null check for the renderer in fl_view_present_layers, clears the renderer reference during disposal, and sinks the renderer's floating reference during engine setup. It also adds unit tests verifying the behavior of presenting layers after destruction across OpenGL, software, and subsurface renderers, as well as the view itself. There are no review comments to evaluate, and I have no additional feedback to provide.
