When source level debug is enabled, but debug cable is not connected,
XhcResetHC() in XhciReg.c will reset the host controller, the debug
capability registers will be also reset. After the code in
InitializeUsbDebugHardware() sets DCE bit and LSE bit to "1" in DCCTRL,
there will be DMA on 0 (the value of some debug capability registers
for data transfer is 0) address buffer, fault info like below will
appear when IOMMU based on VTd is enabled.

de8373fa07 could not handle two cases.
1. For the case that the USB3 debug port instance and DMA buffers are
from PEI HOB with IOMMU enabled, it was to reallocate the DMA buffers
by AllocateAddress with the memory type accessible by SMM environment.
But reallocating the DMA buffers by AllocateAddress may fail.
2. At S3 resume, after the code is transferred to PiSmmCpuDxeSmm from
S3Resume2Pei, HOB is still needed to be used for DMA operation, but
PiSmmCpuDxeSmm has no way to get the HOB at S3 resume.
The patch is to re-support IOMMU.
For PEI, allocate granted DMA buffer from IOMMU PPI, register IOMMU PPI
notification to reinitialize hardware with granted DMA buffer if IOMMU
PPI is not present yet.
For DXE, map DMA buffer by PciIo in PciIo notification for early DXE,
and register DxeSmmReadyToLock notification to reinitialize hardware
with granted DXE DMA buffer accessible by SMM environment for late DXE.
DebugAgentLib has been managing the instance as Handle in
HOB/SystemTable. The Handle(instance) from DebugAgentLib can be used
directly in DebugCommunicationLibUsb3. Then DebugCommunicationLibUsb3
could get consistent Handle(instance) from DebugAgentLib.

Fix GCC build failures below.

The build failure could only be caught with -D SOURCE_DEBUG_USE_USB3

ad6040ec9b needs to be also reverted
when reverting IOMMU support patches, otherwise there will be conflict.
This patch is to re-do ad6040ec9b.

PI 1.6 has supported pre permanent memory page allocation,
to make sure the allocated memory is physical memory for DMA,
the patch is to check memory discovered PPI installed or not first
before calling AllocatePages.

Use CPU Local APIC timer to handle timeout when read data from debug port, instead of the TimerLib in Debug Communication lib instances.
It could remove much duplicated code in Debug Communication Lib instances.

If host sends more than 8 bytes of data, BABBLE error would happen if USB3 debug library uses 8 byte of buffer to read data.
We need use MaxPacketSize in USB3 debug descriptor to create buffer and read data into this buffer.
