Vlv2TbltDevicePkg: Remove Linux/GCC specific DSC/FDF files

* Consolidate DSC/FDF files to remove Linux/GCC specific
  ones.  Since the FCE tool is no longer required, the
  FDF files for building under all supported Host OS
  environments are now the same.

* Update the IA32 and X64 build output directories to use
  a consistent naming convention.

* Make small adjustment to FV layout so everything still
  fits when SOURCE_DEBUG_ENABLE is TRUE.

* Remove unused directories that are not referenced by
  any DSC/FDF files.
