Fred Baksik 72e0c115b7 GHS: Add Compiler ID detection
-- Detect GHS compiler and version
   Detect ARCHITECTURE_ID for PPC / ARM / 86 targets
   Detect PLATFORM_ID for Integrity and Integrity178 platforms
   Using defines specified in the documents for the compilers: 201416 PPC / 201754 ARM / 201714 86
-- Fallback C/CXX compiler ID to GHS if not otherwise detected and using GHS MULTI generator
   Works around issue with some GHS compilers not setting __ghs__ compiler define
-- Tweak Compiler ID checking so major id of 002017 is not replaced with 217
-- Prefer try_compile() library targets when testing for working GHS compilers
-- Avoid CMake errors if reading past end of file for checking if file is PE executable
