stmhal: In USB HID driver, make polling interval configurable.

When setting usb_mode to "HID", hid config object now has
polling-interval (in ms) as the 4th element.  It mmust now be a 5-tuple
of the form:

(subclass, protocol, max_packet_len, polling_interval, report_desc)

The mouse and keyboard defaults have polling interval at 8ms.
