Upgraded all projects to atlasexternals-2.0.145. It brings the following updates wrt. atlasexternals-2.0.144 (atlasexternals@2.0.144...2.0.145):

• Made sure that autoconf/automake based externals would build successfully with CMake >=3.24;
  • This should finally make it possible to switch the master nightlies and the CI to CMake 3.24.3, as discussed in ATLINFR-4765;
• Upgraded the externals in AnalysisBaseExternals to be in sync with LCG_102b_ATLAS_2 (thanks to @elmsheus).

At the same time updated AthAnalysis to use LCG_102b_ATLAS_6, once again in sync with all of the other LCG based projects. (There are some tiny differences between LCG_102b_ATLAS_2 and LCG_102b_ATLAS_6, so the analysis releases will need to be tweaked a bit further later on. But this agreement should be "good enough" to finally get AthAnalysis back in sync with everything else.)

Turning on both full-build and full-unit-tests due to the big external changes in the analysis releases.

Also tagging @krumnack and @amehta.
