Add the python script RunMakefile.py that can be used
in a PREBUILD/POSTBUIILD action to invoke a makefile
passing in context as makefile defines.  The command
line arguments passed into RunMakefile.py are converted
to the following set of defines.

* ACTIVE_PLATFORM
* TARGET_ARCH
* TOOL_CHAIN_TAG
* CONF_DIRECTORY
* TARGET
* EXTRA_FLAGS

In addition, a makefile can access the system environment
variables including WORKSPACE and PACKAGES_PATH.

The makefile target from the following set is also passed
into the makefile.  If no target is passed into build, then
the 'all' target is used.

[all|fds|genc|genmake|clean|cleanall|cleanlib|modules|libraries|run]

A platform DSC file can use a statements in the [Defines]
section of the following form to use this script.  MAKEFILE
is a WORKSPACE or PACKAGES_PATH relative path to the makefile
to run.

[Defines]
  PREBUILD  = python BaseTools/Script/RunMakefile.py --makefile MAKEFILE
  POSTBUILD = python BaseTools/Script/RunMakefile.py --makefile MAKEFILE
