AtlasExternals updates for CC7 Compatibility for 21.9

Updated all projects to atlasexternals-1.0.48.5. The list of changes wrt. atlasexternals-1.0.48.2 (which Athena was using, but every other project was still using atlasexternals-1.0.48...) is the following (atlasexternals@1.0.48.2...1.0.48.4). See also !36624 (merged) and !36899 (merged).

This update should at least allow the compilation of Athena proper to start for the x86_64-centos7-gcc62-opt platform. No changes in output for the x86_64-slc6-gcc62-opt nightly platform are expected.

Please address the warnings reported by the CI. (L1)

added review-user-action-required label and removed review-pending-level-1 label

These warnings are independent of the changes here, and a policy was decided in common with 21.3 that we would not attempt to fix all historical compilation warnings, as discussed in the README for this branch.
