Window DC calls the function set_dc_opengl_drawable( dce-\>hdc, NULL ) to release opengl-drawable through release_dce or release_dc.

After this submission:[**win32u: Don't store the window OpenGL drawables on the DCs.**](https://gitlab.winehq.org/wine/wine/-/merge_requests/8958/diffs?commit_id=c3...) where is the resource release for opengl-drawable? I don't seem to have seen it in this submission. The release of opengl_drawable should be done by the window.
