Allow object to specify the name of processor and processor container
nodes and the UID of processor containers.
This allows these to be more accurately referenced from other tables.
For example for the _PSL method or the UID in the APMT table.
The UID and Name for processor container may be different as if the
intention is to set names as the corresponding affinity level the UID
may need to be different if there are multiple levels of containers.

IoMmuDxe once was designed to support DMA operation when SEV is enabled.
After TDX is enabled in IoMmuDxe, some files' name in IoMmuDxe need to
be more general. So this patch rename:
AmdSevIoMmu.h -> CcIoMmu.h
AmdSevIoMmu.c -> CcIoMmu.c
Accordingly there are some udates in IoMmuDxe.c and IoMmuDxe.inf.

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4171
A typical QEMU fw_cfg read bytes with IOMMU for td guest is that:
(QemuFwCfgReadBytes@QemuFwCfgLib.c is the example)
1) Allocate DMA Access buffer
2) Map actual data buffer
3) start the transfer and wait for the transfer to complete
4) Free DMA Access buffer
5) Un-map actual data buffer
In step 1/2, Private memories are allocated, converted to shared memories.
In Step 4/5 the shared memories are converted to private memories and
accepted again. The final step is to free the pages.
This is time-consuming and impacts td guest's boot perf (both direct boot
and grub boot) badly.
In a typical grub boot, there are about 5000 calls of page allocation and
private/share conversion. Most of page size is less than 32KB.
This patch allocates a memory region and initializes it into pieces of
memory with different sizes. A piece of such memory consists of 2 parts:
the first page is of private memory, and the other pages are shared
memory. This is to meet the layout of common buffer.
When allocating bounce buffer in IoMmuMap(), IoMmuAllocateBounceBuffer()
is called to allocate the buffer. Accordingly when freeing bounce buffer
in IoMmuUnmapWorker(), IoMmuFreeBounceBuffer() is called to free the
bounce buffer. CommonBuffer is allocated by IoMmuAllocateCommonBuffer
and accordingly freed by IoMmuFreeCommonBuffer.
This feature is tested in Intel TDX pre-production platform. It saves up
to hundreds of ms in a grub boot.

Commit 079a58276b98 ("OvmfPkg/AmdSev/SecretPei: Mark SEV launch secret
area as reserved") marked the launch secret area itself (1 page) as
reserved so the guest OS can use it during the lifetime of the OS.
However, the address and size of the secret area held in the
CONFIDENTIAL_COMPUTING_SECRET_LOCATION struct are declared as STATIC in
OVMF (in AmdSev/SecretDxe); therefore there's no guarantee that it will
not be written over by OS data.
Fix this by allocating the memory for the
CONFIDENTIAL_COMPUTING_SECRET_LOCATION struct with the
EfiACPIReclaimMemory memory type to ensure the guest OS will not reuse
this memory.

When running under SEV-ES, a page of shared memory is allocated for the
GHCB during the SEC phase at address 0x809000. This page of memory is
eventually passed to the OS as EfiConventionalMemory. When running
SEV-SNP, this page is not PVALIDATE'd in the RMP table, meaning that if
the guest OS tries to access the page, it will think that the host has
voilated the security guarantees and will likely crash.
This patch validates this page immediately after EDK2 switches to using
the GHCB page allocated for the PEI phase.
This was tested by writing a UEFI application that reads to and writes
from one byte of each page of memory and checks to see if a #VC
exception is generated indicating that the page was not validated.

//
// In the current version, we use the below mapping for TDX:

// 1, 7 | 1 | RTMR[0]

In the current implementation TdMapPcrToMrIndex returns the index of RTMR,
not the MR index.
After fix the spec unconsistent, other related codes are updated
accordingly.
1) The index of event log uses the input MrIndex.
2) MrIndex is decreated by 1 before it is sent for RTMR extending.
