patch 9.0.0917: the WinScrolled autocommand event is not enough

Browse Source 
Problem:    The WinScrolled autocommand event is not enough.
Solution:   Add WinResized and provide information about what changed.

The minimal height and width of a window is set with 'winminheight' and

WinScrolled and WinResized autocommands ~
*win-scrolled-resized*
If you want to get notified of changes in window sizes, the |WinResized|
autocommand event can be used.
If you want to get notified of text in windows scrolling vertically or
horizontally, the |WinScrolled| autocommand event can be used. This will also
trigger in window size changes.
*WinResized-event*
The |WinResized| event is triggered after updating the display, several
windows may have changed size then. A list of the IDs of windows that changed
since last time is provided in the v:event.windows variable, for example:
[1003, 1006]
*WinScrolled-event*
The |WinScrolled| event is triggered after |WinResized|, and also if a window
was scrolled. That can be vertically (the text at the top of the window
changed) or horizontally (when 'wrap' is off or when the first displayed part
of the first line changes). Note that |WinScrolled| will trigger many more
times than |WinResized|, it may slow down editing a bit.
The information provided by |WinScrolled| is a dictionary for each window that
has changes, using the window ID as the key, and a total count of the changes
with the key "all". Example value for |v:event| (|Vim9| syntax):
{
all: {width: 0, height: 2, leftcol: 0, topline: 1, skipcol: 0},
1003: {width: 0, height: -1, leftcol: 0, topline: 0, skipcol: 0},
1006: {width: 0, height: 1, leftcol: 0, topline: 1, skipcol: 0},
}
Note that the "all" entry has the absolute values of the individual windows
accumulated.
If you need more information about what changed, or you want to "debounce" the
events (not handle every event to avoid doing too much work), you may want to
use the `winlayout()` and `getwininfo()` functions.
|WinScrolled| and |WinResized| do not trigger when the first autocommand is
added, only after the first scroll or resize. They may trigger when switching
to another tab page.
The commands executed are expected to not cause window size or scroll changes.
If this happens anyway, the event will trigger again very soon. In other
words: Just before triggering the event, the current sizes and scroll
positions are stored and used to decide whether there was a change.
*E1312*
It is not allowed to change the window layout here (split, close or move
windows).
