vim-patch:partial:9.0.0913: only change in current window triggers the WinScrolled event

Browse Source 
Problem:    Only a change in the current window triggers the WinScrolled
            event.
Solution:   Trigger WinScrolled if any window scrolled or changed size.
            (issue vim/vim#11576)

0a60f79fd0

Skip locking of window layout and E1312.
Copy the latest version of all WinScrolled tests from Vim.
Note: patch 9.0.0915 is needed for the Lua tests to pass.
