implement msc device class

usbd auto stall control for not supported return from class control request
usbd implement xfer isr callback mechanism
DCD
- implement dcd multiple qtd support
- dcd dcd_pipe_stall
- implement dcd_pipe_queue_xfer
- xfer_complete_isr
- flush control endpoint if received new setup while previous transfer is not complete
change msc_cmd_block_wrapper_t flags field to dir
force full speed for easy testing

NOTEs: somehow unable to get endpoint IN interrupt with ioc
