audiod_set_interface used usbd_edpt_clear_stall() on a non-stalled endpoint
purely to drop a leftover BUSY bit ('THIS IS A WORKAROUND!'), from when
ep_close() did not clear endpoint state. That premise no longer holds: by the
time the workaround ran, the endpoint's ep_status (incl. BUSY) had already
been zeroed - by usbd_edpt_close() on close-API ports (ip3511, rusb2) or by
usbd_edpt_iso_activate() on iso-alloc ports - so the call was dead code.
Verified: full audio_test capture works across stop/start streaming (arecord
start -> stop -> restart, each delivering a complete buffer) on stm32f407disco
(dwc2, working iso); 25 raw SET_INTERFACE alt1<->alt0 cycles leave the device
responsive; behaviour is byte-identical with and without the workaround on
metro_m4 (samd51, whose iso-IN stalls for a separate pre-existing reason);
builds clean on iso-alloc (samd, dwc2) and close-API (lpc55, ra) ports.

* license: use SPDX identifiers for src/ headers
Replace the full ~20-line MIT license boilerplate on every src/ file with a
two-line SPDX tag (SPDX-FileCopyrightText + SPDX-License-Identifier), following
the REUSE convention used by CircuitPython and the Linux kernel. Removes ~3500
lines of duplicated boilerplate.

- Added bool is_isr parameter to usbd_edpt_xfer() and usbd_edpt_xfer_fifo() wrapper functions
- These are called by class drivers to queue USB transfers
- Updated all callers to pass false by default (non-ISR context)
- Updated audiod_rx_xfer_isr() and audiod_tx_xfer_isr() to pass true (ISR context)
- All 21 unit tests pass
