[PR] [Fix] Fix the purity flag of "vm.call_tir_dyn" and "kill" ops [tvm]

["MasterJH5574 (via GitHub)" <gi...@apache.org>]

MasterJH5574 opened a new pull request, #16773:
URL: https://github.com/apache/tvm/pull/16773

   This PR fixes the purity flag of `relax.vm.call_tir_dyn` and another few "kill" ops. Their purity flags were set to True, which made them possible to be removed by `remove_all_unused`.
   
   * `relax.vm.call_tir_dyn` works by mutating the input args in place, which is not pure.
   * though the "kill" ops have no actions so far, their semantics suggest that they are impure.
   
   A regression test is added to prevent the unexpected removal from happening again.
