Improve reusability of code that is defined out by cmake build paths

 * Added new ARMNN_STUB_PROFILING and ARMNN_DISABLE_DYNAMIC_BACKEND
   defines to replace BUILD_BARE_METAL and BUILD_EXECUTE_NETWORK_STATIC
 * Add new CMake variables to disable sample apps and dynamic backends
 * Improve BUILD_SHARED_LIBS CMake variable
 * Add new archive output location to various libraries so that the
   static libraries appear in the same location as the shared libraries
 * Fixes for bare metal build
 * Add ARMNN_DISABLE_FILE_SYSTEM defines to missing locations
