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.

It might be useful for the pre-OS payload/checker
to have a handle to the HOB list data for additional
support or data checking that the HOB list contains.

For the pre-OS payload/checker pass in a parameter
that contains additional information for heap space,
heap address, and additional CPU registers that may
need to be set before the pre-OS payload/checker
passes control to the OS.

Some OSes may require a pre-OS checker executable
to run before actually jumping to the OS. Add
support for this pre-OS checker loading & execution
as part of the OS Loader payload when it is compiled
as an FV and when ENABLE_PRE_OS_CHECKER option is
enabled in BoardConfig.py (per the following command):
SblBuild.py build <plat> -p OsLoader.Fv:LLDR:Lz4
The pre-OS checker entry point takes in a single
parameter which provides the CPU boot state that
should be loaded once jumping into the OS for the
pre-OS checker to launch after it finishes execution
(e.g. pre-OS checker does not return to Slim Bootloader).

This patch updates firmware update code to get capsule location
information from configuration data instead of searching in all the
available boot media.
