[Comgr][SPIRV] Write .spv and .bc to file-system with SAVE_TEMPS

If AMD_COMGR_SAVE_TEMPS=1 is set, write the input SPIRV and
output bitocde files to the Comgr temporary directories when
calling the AMD_COMGR_TRANSLATE_SPIRV_TO_BC action.

Also write the paths to the temporary directories to the Comgr log.
