Avoid busy spinning for a potentially long time.

With the buffer / texture mapping acceleration bits working properly, we
can get many outstanding commands and, to avoid blocking the client thread
while waiting for free space, we need a larger queue. 16 MiB was always
enough in my testing (8 MiB wasn't in a few cases).

Keep a lower limit on 32-bit since we're often times address
space-starved there.

Tweaked by Zebediah Figura.

This is to eventually hand frontend and backend resource management
to different code pieces.

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.
