Merge pull request #515 from E3SM-Project/dqwu/fix_adios2_2.9_build_errors

This PR addresses build errors that occur when using ADIOS2 2.9.0
with SCORPIO. Specifically, the deprecated debug mode flag has
been removed to enable successful builds with the latest version
of ADIOS2. This PR ensures that SCORPIO can still be built with
ADIOS2 2.8 as well.
