Reapply "OvmfPkg: VMWare SVGA display device register definitions"

This reverts commit 328409ce8de7f318ee9c929b64302bd361cd1dbd, reapplying
9bcca53fe466cdff397578328d9d87d257aba493.

Note that the commit now being reverted is technically correct; the only
reason we're reverting it is because it should not have been pushed past
the Soft Feature Freeze for the edk2-stable201811 tag.
