refactor: per-worker resource table (#3306)

- removes global `RESOURCE_TABLE` - resource tables are now created per `Worker`
  in `State`
- renames `CliResource` to `StreamResource` and moves all logic related
  to it to `cli/ops/io.rs`
- removes `cli/resources.rs`
- adds `state` argument to `op_read` and `op_write` and consequently adds
  `stateful_minimal_op` to `State`
- IMPORTANT NOTE: workers don't have access to process stdio - this is
  caused by fact that dropping worker would close stdout for process
  (because it's constructed from raw handle, which closes underlying file
  descriptor on drop)
