Deskbar: Improve auto-raise and auto-hide

Activate auto-raise on the screen edge inside the Deskbar window
frame. Set the event mask to B_POINTER_EVENTS when auto-raise or
auto-hide is on and set the event mask back to 0 when we turn off
auto-raise and auto-hide. Before this change you had to click a
window twice to get it to rise above of a raised Deskbar, with
this change you only have to click once to make the window rise
above Deskbar.

The auto-hide show and hide bounds are unchanged.

There was another bug where the window was not hiding correctly in
auto-hide mode when you moused over the status bar in horizontal
mode. This was happening because the where parameter of
TBarView::MouseMoved and TBarView::MouseDown was yielding
coordinates relative to the status tray when the mouse was over
the status tray and not the current view meaning that
TBarView::Frame().Contains(where) would return false over the
status tray. Inspecting the where parameter showed that the x-
coordinate was reset back to 0 when you mouse over the status tray.
To fix this issue I pulled the screen_where field out of
CurrentMessage() instead since this yields the correct value.

The calendar window input focus has been fixed in auto-raise mode
so that you can click on calendar even when it is above Deskbar.
You may also click a window on top of Deskbar in auto-raise mode
without the Deskbar window being raised.

Don't hide Deskbar when Calendar is showing in auto-hide mode.

Put comment inside else block inside { }.

Return from TBarView::MouseDown() calling ansestor method.

Quit fCalendarWindow on TimeView deconstructor if it exists (even if
it is not curently being shown.)

Fixes #8923 #14493
