Log Message:
Make sure to add "extern C" block around program-only declarations (#28965)

This PR fixes nightly testing errors for ROCM7 gpu testing. Add an
extern "C" block around a set of program-only symbol declarations
(that really should have been declared as such in the first place).

TESTING

  • standard
  • Build on hpe-cray-ex CHPL_LOCALE_MODEL=gpu w/ ROCM7
  • COMM=gasnet
  • gasnet-asan w/ fastAndIncremental.chpl
