Laszlo Ersek 4d1362e1f9 OvmfPkg/PlatformDxe: eliminate unchecked PcdSetXX() calls
These are deprecated / disabled under the
DISABLE_NEW_DEPRECATED_INTERFACES feature test macro.

Introduce a variable called PcdStatus, and use it to assert the success of
these operations (there is no reason for them to fail here).

Laszlo Ersek 92e745505c OvmfPkg: PlatformDxe: add form widgets for video modes
In this patch we populate the form with the two widgets related to video
resolution:
- A read-only string field displaying the preference for the next boot.
- A drop-down list offering choices for changing the setting. This list is
  implemented with dynamically generated IFR opcodes.

(In general, the current preference may be missing, or it may be invalid
for the available video RAM size. The list of possible new settings is
filtered with the video RAM size.)

Because the form now becomes able to receive input, we must also implement
ExtractConfig(). This function tells the HII engine about the state of the
widgets.

For now we set up both widgets with static data only:
- The current preference always says "Unset". The driver code is still
  isolated from the backend (the UEFI variable store).
- The list of possible resolutions offers 800x600 only. We don't
  interrogate the GOP yet.

Laszlo Ersek bdaf30e4e6 OvmfPkg: PlatformDxe: set preferred video resolution from platform config
The GraphicsConsoleDxe driver (in MdeModulePkg/Universal/Console)
determines the preferred video resolution from the dynamic PCDs
- gEfiMdeModulePkgTokenSpaceGuid.PcdVideoHorizontalResolution
- gEfiMdeModulePkgTokenSpaceGuid.PcdVideoVerticalResolution

Setting the graphics resolution during boot is useful when the guest OS
(for lack of a dedicated display driver) continues to work with the
original GOP resolution and framebuffer.
