Add the AUTH_SIG_NOT_FOUND Action to the Image Execution Info Table
when the Image is signed but signature is not allowed by DB and the
hash of image is not found in DB/DBX.
This is documented in the UEFI spec 2.10, table 32.5.
This issue is found by the SIE SCT with the error message as follows:

Call gRT->GetVariable() directly to read the SecureBoot variable. It is
one byte in size so we can easily place it on the stack instead of
having GetEfiGlobalVariable2() allocate it for us, which avoids a few
possible error cases.
Skip secure boot checks if (and only if):
(a) the SecureBoot variable is not present (EFI_NOT_FOUND) according to
the return value, or
(b) the SecureBoot variable was read successfully and is set to
SECURE_BOOT_MODE_DISABLE.
Previously the code skipped the secure boot checks on *any*
gRT->GetVariable() error (GetEfiGlobalVariable2 sets the variable
value to NULL in that case) and also on memory allocation failures.

RngGetBytes() relies on the RngLib. The RngLib might use the RNDR
instruction if the FEAT_RNG feature is present. RngGetInfo and
RngGetRNG both must check that RngGetBytes() is working before
advertising/using it.
To do so, allocate an array storing the available algorithms.
The Rng algorithm at the lowest index will be the default Rng
algorithm. The array is shared between RngGetInfo and RngGetRNG.
This array is allocated when the driver is loaded, and freed
when unloaded.
This patch also prevents from having PcdCpuRngSupportedAlgorithm
let to a zero GUID, but let the possibility to have no valid Rng

RngGetInfo() is one of the 2 functions of the EFI_RNG_PROTOCOL.
RngGetInfo() is currently a mere wrapper around
ArchGetSupportedRngAlgorithms() which is implemented differently
depending on the architecture used.
RngGetInfo() does nothing more than calling
ArchGetSupportedRngAlgorithms(). So remove it, and let RngGetInfo()
be implemented differently according to the architecture.
This follows the implementation of the other function of the
EFI_RNG_PROTOCOL, RngGetRNG().

gEfiRngAlgorithmSp80090Ctr256Guid was used as the default algorithm
in RngGetRNG(). The commit below set the default algorithm to
PcdCpuRngSupportedAlgorithm, which is a zero GUID by default.
As the Pcd value is not defined for any platform in the edk2-platfoms
repository, assume it was an error and go back to the first version,
using gEfiRngAlgorithmSp80090Ctr256Guid.

EFI_CC_EVENT_HOB_GUID is the global ID of a GUIDed HOB used to pass
TDX_DIGEST_VALUE from SEC to a DXE Driver ( This DXE driver will
be introduced in the following commit in this patch-sets ). In that
DXE driver this GUIDed HOB will be parsed and the TDX_DIGEST_VALUE
then will be extracted. After that a EFI_CC_EVENT will be created
based on it.

RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3853
This library provides hash service by registered hash handler in Td
guest. Currently only SHA384 is supported. After that the hash value is
extended to Td RTMR registers which is similar to TPM PCRs.

In V2: Fixed patch format and uncrustify cleanup
In V1: To follow the TCG CRB protocol specification, on every CRB TPM
command completion the TPM should return to Idle state, regardless of
the CRB Idle Bypass capability reported by the TPM device.
See: TCG PC Client Device Driver Design Principles for TPM 2.0,
Version 1.0, Rev 0.27

In V4: Fixed patch format and uncrustify cleanup
In V3: Cleaned up comments, debug prints and updated patch to use the
new debug ENUM definitions.
- Replaced EFI_D_INFO with DEBUG_INFO.
- Replaced EFI_D_VERBOSE with DEBUG_VERBOSE.
In V2: Add case to RegisterHashInterfaceLib logic
RegisterHashInterfaceLib needs to correctly handle registering the HashLib
instance supported algorithm bitmap when PcdTpm2HashMask is set to zero.
The current implementation of SyncPcrAllocationsAndPcrMask() triggers
PCR bank reallocation only based on the intersection between
TpmActivePcrBanks and PcdTpm2HashMask.
When the software HashLibBaseCryptoRouter solution is used, no PCR bank
reallocation is occurring based on the supported hashing algorithms
registered by the HashLib instances.
Need to have an additional check for the intersection between the
TpmActivePcrBanks and the PcdTcg2HashAlgorithmBitmap populated by the
HashLib instances present on the platform's BIOS.
