chip/stm32/usb: Add support for USB SET_FEATURE control requests
This is required so that the kernel can enable/disable remote wake-up
capabilities, and in particular for the kernel to enable autosuspend.
Also, properly implement GET_STATUS.
BRANCH=none
BUG=b:35579996
TEST=echo auto > /sys/bus/usb/drivers/usb/X-Y/power/control, device
autosuspends after 2 seconds, and wakes on keypress.
Note that this introduces other bugs, where keys are missing,
repeated, see b/35775048.
