allow a limited model to deal with stalled pipe/transaction

added stall clear & able to mount the stupid toshiba thumb drive

add HCD pipe API
- bool hcd_pipe_is_busy(pipe_handle_t pipe_hdl);
- bool hcd_pipe_is_stalled(pipe_handle_t pipe_hdl);
- uint8_t hcd_pipe_get_endpoint_addr(pipe_handle_t pipe_hdl);
- tusb_error_t hcd_pipe_clear_stall(pipe_handle_t pipe_hdl);

remove tusbh_device_mount_failed_cb (not neccessary for user)
