sdl2: Support all virtio-gpu formats

Browse Source

There are some 2D resource formats that can be used through virtio-gpu,
but which are not supported by SDL2 when used for a scanout; these are
all alpha-channel formats and also XBGR (RGBX in non-BE pixman).

Add these formats in the switch converting pixman to SDL format
constants so a guest cannot crash the VM by triggering the
g_assert_not_reached() with an unsupported format.
