OvmfPkg: copy SataControllerDxe from DuetPkg

Edk2 maintainers reached the consensus that SataControllerDxe was
inherently platform specific, for which reason it was not appropriate for
either PcAtChipsetPkg nor MdeModulePkg. Hence, if OvmfPkg wanted to use
it, it should either reference it directly from under DuetPkg, or copy it.

Given that DuetPkg is another "leaf" platform in edk2, and that in the
upcoming patches we'll actually modify the driver, the ultimate decision
(reached months ago on the list, after Reza's v2 posting) is that OvmfPkg
shall copy the driver.

This patch does that; the only difference being a fresh FILE_GUID in the
INF file.
