Update CMake configuration to adopt a more modern style

[tmadlener]

BEGINRELEASENOTES

• Adopt cmake configuration to use the target based style of configuring
• Raise the minimum version of cmake to 3.23
  • Keep existing behavior by enabling cmake policy CMP0033
• Fix dependencies to rely on LCIO instead of Marlin (since Marlin is not truly a dependency, but LCIO is).
• Make ROOT a required dependency since building without ROOT is not possible
• Export targets for downstream consumption with pure cmake functionality. The exported target is MarlinKinfit::MarlinKinfit.

ENDRELEASENOTES

• Needs Remove the FindGSL module since its provided by CMake iLCUtil#38 to be available from the nightlies

I have tested this locally and the stack builds without changes. Usage of the target in downstream packages can start with the next release most likely.

release based CI is failing because the necessary ilcutil PR is not yet there.
