The FV in `IntelTdx/IntelTdxX64.fdf` was split into two FVs, one for a
TD guest and one for non-cc guest. The SCSI driver was moved to the
non-cc NCCFV. In order for PVE to use an image with SCSI include the
SCSI driver in the FV for TD guest.

Change variable and function names that are specific to AMD SEV to
reflect this. Also, change name of general CC functions and variable
names to be used in conjunction with other platforms.

Check whether TDX is enabled on this machine. Instead of using CPUID
like AMD SEV, Intel TDX enablement can be verified by reading an MSR

To: pve-devel; +Cc: Philipp Giersfeld
From: Philipp Giersfeld <philipp.giersfeld@canarybit.eu>
This commit adds support for setting up an Intel TDX VM. A Intel TDX VM
can be setup similar to AMD SEV but uses a different firmware image.
