sysview: instrument usbd/usbh, dcd/hcd and class-driver call sites
Level 2 marks the stack's task-side entry points (tud_task/tuh_task inner
loop, usbd_edpt_xfer, control transfers); level 3 adds the class drivers
(cdc, msc) and the rp2040 dcd/hcd as the reference portable layer. All
call sites compile away below their level.
