patch 9.0.2106: [security]: Use-after-free in win_close()
Commit: https://github.com/vim/vim/commit/25aabc2b8ee1e19ced6f4da9d866cf9378fc4c5a

patch 9.0.2106: [security]: Use-after-free in win_close()
Problem: [security]: Use-after-free in win_close()
Solution: Check window is valid, before accessing it
If the current window structure is no longer valid (because a previous
autocommand has already freed this window), fail and return before
attempting to set win->w_closing variable.
Add a test to trigger ASAN in CI
