Issue with register reset annotations and tofino-model:

It takes ~70ms to reset 65k register cells on HW
- Better to spin up separate thread
Add --testing-tofino-model (default false) to:
- Disable register reset
- Use longer timeouts for counter syncs
OR: Use pal API to get type of device (model or asic)
- include/tofino/bf_pal/pltfm_intf.h
- bf_status_t bf_pal_pltfm_type_get(bf_dev_id_t dev_id, bool *is_sw_model);
