Cherry-pick CL 1250286 from SC stg.

HSA Finalizer: Add dumping of code object, ISA and executable to loader.

This is controlled by loader options -dump-all, -dump-isa, -dump-code, -dump-exec

The options can now also be set with env variable LOADER_OPTIONS_APPEND.

Added tests to finalizer_offline

Testing: smoke, dumping on hardware
