Generalize support for Portland Group Compiler

We factor flags from Platform/Linux-PGI-Fortran.cmake into language
independent helper modules

  Compiler/PGI.cmake
  Platform/Linux-PGI.cmake

and invoke the macros from

  Compiler/PGI-<lang>.cmake
  Platform/Linux-PGI-<lang>.cmake

This enables general support for the PGI compilers.
