(1) This patch will break ArmVirtPkg, because the following two
additional DSC files include QemuVideoDxe.inf:

  ArmVirtPkg/ArmVirtQemu.dsc
  ArmVirtPkg/ArmVirtQemuKernel.dsc

So please split up this patch as follows:
- patch 5 -- FrameBufferBltLib class resolution for ArmVirtPkg (2 DSCs),
- patch 6 -- FrameBufferBltLib class resolution for OvmfPkg (3 DSCs),
- patch 7 -- QemuVideoDxe changes.

(2) I think you missed the FrameBufferBltLib resolution in "OvmfPkgX64.dsc".

(3) This hunk is unnecessary; you never reference the new field
QEMU_VIDEO_MODE_DATA.FrameBufferConfigure.

The rest of this patch looks okay to me.
