[bazel,ci] Use a single-threaded Verilator model in CI

This commit runs a single-threaded Verilator model in CI due to
constrained compute resources.

- The `verilator_options` flag is exposed via a Bazel configuration to
  allow the `--threads` flag to be set from the command line. By
  default, `--threads 4` is passed if the option is not specified
- The scripts used to build the Verilator model demonstrate how this flag
  should be used
