When specify a payload file in the build command line, the current
searching folder is: PayloadPkg/PayloadBins, Platform/$(PlatformBoardPkg)
/Binaries. This patch added another searching folder in the Build FV
if the payload file cannot be found in the listed folders above. This
is useful when the payload image itself is generated from the build
process.

Current QEMU build will produce many different SPI layouts due to
different build feature flags, such as source level debug support.
Since QEMU is a virtual platform, it is better to relax the size
so as to have consistent SPI layout. It will make it easier for
debug. This patch produces fixed QEMU image size (2MB).

This patch added a simple parser for grub.cfg to make it easy to boot
Ubuntu ISO image using OsLoader payload. Without it, it is required to
copy vmlinuz/initrd to root directory and create a config.cfg to list
the kernel boot command line in order to boot the ISO image. This patch
makes it possible to boot the original Ubuntu ISO (16.04 or 18.04)
directly. It provides better user experience for people who wants to
try out SBL.
Please note, same as before, when verified boot is enabled, only debug
build will support this feature. Release build will disable this feature
due to security concern, please use IAS image boot mechnism instead.

Current SBL can only support on VBT file. However, different board
might need different VBT table. It is better to have the capability
to embed multiple VBT table into the image. This patch implemented
this feature and enabled it on QEMU. By default, it will take the
original behavior. if _MULTI_VBT_FILE in BoardConfig.py is specified,
multiple VBT files can be used.
If multiple VBT table support is required, list them as:
{VbtImageId1 :VbtFileName1, VbtImageId2 : VbtFileName2, ...}
VbtImageId is ID to identify a VBT image. It is a UINT32 number to
match the ImageId field in the VBT container.
VbtFileName is the VBT file name. It needs to be located under platform
VbtBin folder.

SBL has no intention to support SMI. However, on many hardware
platforms, there is no reliable way to prevent SMI from generating
through SMI IPI. In case it occurs, CPU will jump to the default
0x38000 location for execution, which exposes huge security issues.
The recommended solution is to do basic SMM base relocation and put
a dummy SMI handler (RSM) there for platform does not support SMI
disabling. In this way, the SMI will be ignored, and it also closes
the security concerns. This patch implemented basic SMM relocation.
It is under the control of a new PCD PcdSmmRebaseEnabled. By default,
it is disabled. To enable it, please set ENABLE_SMM_REBASE in
BoardConfig.py. As part of it, platform library needs to set
PcdSmramTsegBase and PcdSmramTsegSize properly in PreSiliconInit board
hook. Please take APL platform for reference.

Previous USB keyboard console support commit worked fine on APL real
platform, but it has issue on QEMU. This patch further enables USB
keyboard console support for QEMU. A new PcdUsbKeyboardPollingTimeout
is added. It will be used to control the USB keyboard interrupt
transfer polling timeout. For QEMU, it needs a larger number due to
timing issue. As part of it, booting from USB device is also enabled
by this patch. This patch fixes#30.
To test USB keyboard console in QEMU, please first change
CONSOLE_IN _DEVICE_MASK in BoardConfig.py to 3, and then add the
following in the QEMU command line to add XHCI controller and USB KB:

* Enable DebugAgentLib to support source level debug over serial
By default, source level debug is NOT enabled. ENABLE_SOURCE_DEBUG
needs to be set to 1 in BoardConfig.py of each Platforms.

As an initial drop, there are some limitations on APL platform.
- Stage1A does not include DebugAgentLib due to Stage1A size
limitation(32KB). Further optimization is required.
- DebugAgentLib supports ONLY POSTMEM debugging on APL currently.
