OvmfPkg/Sec: Move SEV-ES SEC workarea definition to common header file
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3108
In order to allow for the SEV-ES workarea to be used for other purposes
and by other files, move the definition into the BaseMemEncryptSevLib
header file, MemEncryptSevLib.h.
