[RFC v2 0/2] Support Union type in VFR

[Dandan Bi <dandan.bi@intel.com>]

V2: Update VfrCompiler to use member variable instead of global varable
to indicate whether current date type is Union.

This serie is the POC to update VfrCompiler to support Union type
in VarStore and construct the use cases in DriverSample.
