resolve a noisy cmake deprecation warning when using latest cmake version

[spoonincode]

latest cmake 3.31 has started to produce warnings such as

CMake Deprecation Warning at libraries/eos-vm/CMakeLists.txt:5 (cmake_minimum_required):
  Compatibility with CMake < 3.10 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.

A variation of this is printed over 10 times for spring. Resolve this warning for projects we control. Needs also,
AntelopeIO/abieos#36
AntelopeIO/appbase#38
AntelopeIO/chainbase#55
AntelopeIO/eos-vm#29

Thanks for the reviews; I still need another one on the linked AntelopeIO/abieos#36. It will help getting this merged before submodules continue to drift out which is a real pain.
