9939f2e353 config_tools/upgrader: keep cache allocation policies properly
The current generic data moving policy in the upgrader do not work well
with complex nodes having multiple-occurred descendants. That causes the
lost of cache allocation policies in scenario XMLs when upgrading a v3.0
scenario XML to the coming v3.1.

This patch adds another generic-purpose mover that simply copies a whole
subtree unchanged.

Most nodes of this kind are handled by special movers as their formats
changed dramatically in v3.0, which is why that issue is not identified
earlier.

df68c7ad2e config_tools: support dynamic enum names in XML schema
The dynamic enum mechanism today only allows specifying the enum values
using XPATH. While this is sufficient from functionality point of view, it
may not provide the best experience as users have to understand the raw
data used internally. The typical way to present more informational labels
of enum values to users is enum names which cannot be supported by the
current XML schema to JSONSchema converter.

This patch allows the XML schema to specify dynamic enum names by adding an
`acrn:option-names` attribute to an element. The attribute is interpreted
as an XPATH which evaluates to a sequence of the same length of
`acrn-options`. The element at index i in that sequence is considered the
enum name of the enum value at index i of the results of `acrn:options`.

This mechanism is first applied to the `pcpu_id` element to indicate
whether a physical CPU is P-core or E-core.

5676cceda0 ACRN:DM:Vdisplay: Render one small bogus texture to fix the display issue in multi render_context
When virtio-gpu is used for guest_vm, ACRN uses the libSDL API to render the framebuffer
submitted from guest virtio-gpu device. The libSDL will cache some op/states related with
3D internally and skip some 3D API. This works well for one display. When multi displays
are enabled, ACRN will create  one SDL_Renderer/SDL_window for each display_window.
As the libSDL caches some states, it can't select the correct 3D shader and show
the garbage when switching among multi SDL_Renderer.

This is one limitation in libSDL.
So one small texture(32x32) is created and rendered so that each time it can reconfigure
the internal state for target texture. This is used to workaround the display issue.

516e8ef4b1 ACRN:DM:VGPU: Add virtio_gpu_scanout structure to handle virtio-gpu-cmds correctly
Now it only supports one scanout for virtio-gpu. So the scanout_id is ignored in
course of handling virtio-gpu cmd. In order to handle the virtio-gpu cmd correctly,
it adds the virtio_gpu_scanout structure so that it can record the scanout info.

v1->v2: Refine the field in virtio_gpu_scanout and error message for scanout_id

6407de302c ACRN:DM:VDisplay: vdpy_init connection returns the supported number of vScreen
Vdisplay module will create the gui_window (vScreen) based on the virtio-gpu
parameter. When virtio-gpu device tries to establish the connection with
vdisplay module, it will return the supported number of vScreen.
Then the virtio-gpu device can initialize the correct info for the guest_vm.

BTW: The number is fixed to 1.
