  Log Message:
  -----------
  [HIP] compressed bundle format defaults to v3 (#152600)

HIP runtime support for compressed bundle format v3 is in place,
therefore switch the default compressed bundle format to v3 in compiler.

This allows both compressed and decompressed fat binary size to exceed
4GB by default.

Environment variable COMPRESSED_BUNDLE_FORMAT_VERSION=2 can be used for
backward compatibility for older HIP runtimes not supporting v3.

Fixes: SWDEV-548879
