Configuration of ATLAS Detector Description using ComponentAccumulator

See merge request atlas/athena!20770

Update reference file comparison so as to not fail if SimFlags are
not available.

Should fix ATLASSIM-4013.

This commit adds an initial attempt add configuring the description of the
whole ATLAS detector in GeoModel using ComponentAccumulator.

It also adds tests for building the full Atlas geometry based on different
input file types.

Update Output ConfigFlags in AllConfigFlags module.
- Replace `Output.HITFileName` with `Output.HITSFileName` to match
grid output naming convention.
- Add `Output.EVNTFileName`.

Add default HITS and EVNT and ESD input files for tests to AthenaConfiguration.TestDefaults module
