usbd_control: consolidate status stage ep selection
Extract the "which endpoint is the Status stage on" rule into a single
TU_ATTR_ALWAYS_INLINE helper, and use it from both status_stage_xact()
and the completion callback. Replaces the two-operand wLength/direction
check with a direct endpoint-match comparison, matching the first
operand's pattern.
Per USB 2.0 ยง9.3.1, when wLength == 0 the bmRequestType Direction bit
is ignored and the Status stage is always IN; otherwise the Status
stage is opposite to the Data stage direction.
