change(usb/host): Remove data buffer headers from URBs
This commit removes the ability to reserve a header in the data buffer of an
allocated URB. The header was required for a now defunct implementation of a
synchronous USB Host library API. Thus, headers are no longer required in
URB data buffers.

accbaee57c Add USB Host Library
This commit adds the preliminary version of the USB Host Library. This commit contains:

- USBH (USB Host Driver)
- Hub Driver that only supports a single device and device enumeration
- USB Host Library (asychronous API)
- Test cases for USB Host Library asychronous API

The following changes were made to the existing HCD:
- Removed HCD_PIPE_STATE_INVALID. Pipes are no longer invalidated
- Changed pipe commands to halt, flush, and clear. Pipes need to be manually
  halted, flush, and cleared.
- Halting and flushing a pipe will execute the pipe callback if it causes a
  HCD_PIPE_EVENT_URB_DONE event
