OvmfPkg: Introduce XenResetVector Introduce XenResetVector, a copy of OvmfPkg/ResetVector, with one changes: - SEC_DEFAULT_CR0: enable cache (bit 30 or CD set to 0) Xen copies the OVMF code to RAM, there is no need to disable cache. This new module will later be modified to add a new entry point, more detail in a following commit "OvmfPkg/XenResetVector: Add new entry point for Xen PVH" Value FILE_GUID of XenResetVector have not changed compare to ResetVector because it is a special value (gEfiFirmwareVolumeTopFileGuid).

OvmfPkg/XenResetVector: Saving start of day pointer for PVH guests As described in the Xen PVH documentation [1], "ebx: contains the physical memory address where the loader has placed the boot start info structure". To have this pointer saved to be able to use it later in the PEI phase, we allocate some space in the MEMFD for it. We use 'XPVH' as a signature (for "Xen PVH").
