[edk2-platforms] [PATCH v2 4/4] Platform/Intel: Add FIT generation tool

["Agyeman, Prince" <prince.agyeman@intel.com>]

Added FitGen tool build and FIT generation
to the BIOS build process.

What was done:

- Build the FIT generation tool
- Added default/empty BIOS_INFO_GUID to the build.cfg
- Added BIOS_INFO_GUID to GalagoPro3,KabylakeRvp3
and WhiskeylakeURvp's build_config.cfg
This allows a board to specify the GUID
associated with the BIOS Info PEIM to be used
in the board's FIT generation.

BIOS_INFO_GUID is passed as an argument to
FitGen tool which allow the tool to locate
the BIOS Info module to be used in FIT generation.
