This is to eventually allow d3d12_swapchain_queue_present() to
operate on a certain VkImage even if current_buffer_index has
already been modified since the corresponding Present() call.

This is an oversight in eec9c3a2:
vk_format specifies the format used for the frontend resources. The backend
images could use a different format, depending on what the swapchain
supports.

Also, introduce the terms "frontend" and "backend" for the two sides
of the swapchain, which are probably easier to understand.

Needed for Revo Scan 5.

Needed by IBluetoothAdapter in windows.devices.bluetooth.idl.

This is used by ARM64EC importlibs.

The graphics driver information is stored as a property in the desktop window. When the server
get_desktop_window handler simply returns a window handle when the window station is invisible,
the window handle doesn't have the graphics driver property, which is set in desktop_window_proc()
when handling WM_NCCREATE. Removing the invisible window station check allows an invisible explorer
desktop window to be created and with the required property.

Having an invisible window station doesn't mean an application is running in a service context. For
example, Chromium creates a sandbox process to run in an invisible window station and still expect
the physical monitor information to be returned, instead of the virtual monitor information for
services.

Test that processes running with an invisible window station have physical monitor information
instead of the virtual monitor information used for services.

Chromium creates a suspended sandbox process with a token of limited access. Then it sets a token
with normal access for the main thread of the newly created process. Without this change, explorer
is started with the process token of limited access and fails to create a desktop window.
