OsLoader has the capability to boot a Linux kernel. However, to support
LinuxBoot type of payload, it is required to load kernel in Stage2. This
patch abstracts the standard Linux loading logic into common LinuxLib
class so that it can be linked in Stage2 or Payload such as OsLoader.
A new PcdLinuxPayloadEnabled is introduced to control if this feature
should be enabled or not.
To boot a Linux kernel from Stage2, it is required to put the command
line file and kernel image into the EPAYLOAD container during the build.
And the PayloadId CFGDATA needs to be set to 'LINX'.
For example:
python BuildLoader.py build qemu
-p OsLoader.efi::Lz4;vmlinuz:LINX:Dummy;cmdline.txt:CMDL:Dummy
vmlinuz and cmdkube.txt need to be copied to PayloadPkg/PayloadBins
folder. If kernel size cannot fit into EPAYLOAD, EPAYLOAD_SIZE in
BoardConfig.py needs to be adjusted accordingly.

This patch added a ContainerLib to support load and location a
component from a specified container. It copies the component
from flash to memory, authenticate it, and then decompress it if
required. It can also be used to support load component from flash
map in SBL stage2 or payload, such as payload or e-payload.

Common MM_PCI_ADDRESS() provided PCI device BDF to PCIE MMIO base address.
So remove MmPciAddress() and MmPciBase () defined in platform and update
code to use MM_PCI_ADDRESS().
Add TO_PCI_LIB_ADDRESS() in common library.

Current SBL depends on GEN_CFG_DATA.PayloadId to determine which payload
to boot if multiple payloads exist. With this patch, when PayloadId is
set to "AUTO", QEMU will use the QEMU command line parameter
'-boot order' to determine which payload to boot.
For example, adding '-boot order=dba' in QEMU commadn line will boot to
UEFI payload. This provides a simple way to test different payloads using
the same SBL image.

Smm bases for all the procs need to be relocated on the
S3 resume path (as payload is not run) for Windows boot.

LOADER_GLOBAL_DATA.LdrFeatures is updated in early stages and
subsequent stages could use these flags.
LOADER_PLATFORM_INFO.LdrFeatures is used to for feature updates
and this need to be checked by loader and payloads.
LOADER_PLATFORM_INFO.HwState for Hw supported features as
Boot guard profiles.
