user32/edit: Don't use WM_TIMER to update caret position.

An application subclasses edit control and crashes on unexpected WM_TIMER
messages. A timer was
    added a long time ago and it was for auto scrolling the view when the
cursor is outside of the
    client area. However, with a EDIT_EM_ScrollCaret() call in
EDIT_WM_MouseMove(), the view can be
    scrolled to the correct position automatically. So the timer is not
necessary at all. This is tested
    manually with a long text in the edit control with notepad on XP, Win7 and
Win10. Before this patch,
    the caret will move backwards every 100ms when the clicking the left mouse
button on the bottom of
    the text and then dragging the cursor upwards and outside of the client
area. After this, the
    behavior is the same as native.
