Make ExplicitDynamicsContact Action block restrictable

[WilkAndy]

Motivation

For two reasons:

1. I've found that calculating AuxKernels takes a significant amount of walltime in explicit simulations. If we can block-restrict the AuxVariables that ExplicitDynamicsContact creates, that walltime will reduce.
2. It may be that we don't want AuxVariables defined on a particular block. Eg, that block corresponds to "removed" material, and it makes no sense to calculate AuxKernels on it.

Design

Probably just add something like

  params.addParam<std::vector<SubdomainName>>(
      "block",
      {},
      "Optional list of subdomain names on which to create the contact MooseObjects.  If omitt\
ed, MooseObjects will be created on all subdomains");

    _blocks(getParam<std::vector<SubdomainName>>("block"))

      if (!_blocks.empty())
        var_params.set<std::vector<SubdomainName>>("block") = _blocks;

Impact

Enhance the ExplicitDynamicsContactAction

Yep, @GiudGiud , i've got a PR ready to go, but would prefer that #30853 were merged first
