BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3902
The confidential computing guest type (GUEST_TYPE) was defined in
OvmfPkg/Include/WorkArea.h. Now it is to be moved to
MdePkg/Include/ConfidentialComputingGuestAttr.h and renamed as
CC_GUEST_TYPE.
There are 2 reasons for this change.
1. CC_GUEST_TYPE is a generic definition and will be used in CcProbeLib
which is defined in MdePkg.
2. Based on the latest edk2 coding style:
- First character should be upper case
- Must contain lower case characters
- No white space characters
- Global variable name must start with a 'g'
As the first step CC_GUEST_TYPE is defined in this patch. In the
next patch GUEST_TYPE will be deleted. This is to make sure the
bisect work correctly.
