OvmfPkg/VmgExitLib: Set the SW exit fields when performing VMGEXIT
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3008 All fields that are set in the GHCB should have their associated bit in the GHCB ValidBitmap field set. Add support to set the bits for the software exit information fields when performing a VMGEXIT (SwExitCode, SwExitInfo1, SwExitInfo2).
