[DO NOT MERGE] Usb Gadget HAL: modify monitorfs behavior

Currently, monitorffs will pull up gadget when the ffs
endpoints are ready. When the device change the data
role from peripheral to host, the pullup behavior will
still occur. It will cause the host mode and peripheral
mode start in the same time.

This patch will check typec and USB gadget state before
pulling up gadget.
