TDVF enables UEFI support for TDX virtual machines. Add a build target
to build TDFV in Config-B (https://github.com/tianocore/edk2/tree/master/OvmfPkg/IntelTdx#configurations-and-features)
Config-B better conforms to the Intel TDX threat model and is preferred
over Config-A.

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.

To: pve-devel
Add configuration options for the quote-generation-socket used to
communicate with the Quote Generation Service. This enables attestation
support for TDX using vsock or unix sockets.
More information can be found at:
https://www.qemu.org/docs/master/interop/qemu-storage-daemon-qmp-ref.html#object-QSD-qom.TdxGuestProperties
This only includes support for vsock and unix sockets. The SocketAddress
object in QEMU also supports inet and fd, which are not commonly used in
TDX.

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 the MSR
(https://cc-enabling.trustedservices.intel.com/intel-tdx-enabling-guide/05/host_os_setup/).

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.
Intel TDX requires kernel_irqchip to be set to `split`, instead of the
default `on`. QEMU does change the default for TDX guests, but it is
included explicitly here for clarity.

Extend the tdx object with the quote-generation-socket as defined in:
https://www.qemu.org/docs/master/interop/qemu-storage-daemon-qmp-ref.html#object-QSD-qom.TdxGuestProperties
Only vsock and unix sockets are included here since they are the most
commonly used socket types with TDX attestation.
