OvmfPkg: VMWare SVGA display device register definitions
This adds a header file defining symbolic constants for the VMWare SVGA virtual display device in preparation for supporting it in QemuVideoDxe. It is mostly an extract of the file lib/vmware/svga_reg.h from commit 329dd537456f93a806841ec8a8213aed11395def of VMWare's vmware-svga repository at git://git.code.sf.net/p/vmware-svga/git (See also http://vmware-svga.sourceforge.net/ ) Only the bare essentials necessary for initialisation, modesetting and framebuffer access have been kept from the original file; macro names have been prefixed with VMWARE_SVGA_ instead of SVGA2_, and the enum definition has been adapted to comply with EDK2 naming conventions. The original file was released by VMWare under the MIT license, this has been retained.
