WindowServer+LibGfx: Move normal window frame painting to a WindowTheme This patch introduces the ClassicWindowTheme, which is our default theme implemented as a Gfx::WindowTheme subclass. In this initial cut, we move normal window frame painting and title bar metrics helpers out of WindowServer and into LibGfx. This will eventually allow us much greater flexibility with theming windows, and also makes it easier to build applications that want to render a window with a specific style for some reason. :^)

WindowServer+LibGUI+LibGfx: Add WindowType::ToolWindow Tool windows are secondary windows with a smaller title bar. The sit on the layer above normal windows, and cannot be minimized. These are intended for complex yet non-modal interactions with the content of a primary window, such as find/replace windows, property windows, etc.

WindowServer+LibGfx: Rename menu_bar => menubar We had a mix of "menu_bar" and "menubar". Let's just use "menubar" everywhere since that feels the most natural to write.

WindowServer+LibGfx: Show menus in windows! :^) This patch begins the transition away from the global menu towards per-window menus instead. The global menu looks neat, but has always felt clunky, and there are a number of usability problems with it, especially in programs with multiple windows. You can now call GUI::Window::set_menubar() to add a menubar to your window. It will be specific to that one window only.

WindowServer: Implement simple window shadows This implements simple window shadows around most windows, including tooltips. Because this method uses a bitmap for the shadow bits, it is limited to rectangular window frames. For non-rectangular window frames we'll need to implement a more sophisticated algorithm.

LibGfx: Fix classic theme frame transparency check We shouldn't use the title stripe or title shadow colors to determine whether the frame itself is going to have alpha channels or not. This caused e.g. the classic theme's window frame to be rendered as transparency just because the stripe color had an alpha channel of 0.

// We don't care about the title_stripes_color or title_shadow_color alpha channels because they are
// effectively rendered on top of the borders and don't mean whether the frame itself atually has
