* 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.

Even if CFG_TUH_MIDI_RX_BUFSIZE=100*TUH_EPSIZE_BULK_MAX, calling tuh_midi_stream_read without a loop can return only one 4-byte packet and preventing subsequent transfer.

Follow-up to #3239. tuh_midi_stream_read terminates on cable-number
transitions, leaving residue in the FIFO. With the default RX FIFO
sized equal to one bulk packet, the next bulk IN transfer fails to
queue and the driver silently stops receiving. Raising the default
to 2x bulk gives single-call apps a full packet of headroom and
documents the drain-loop expectation.
Reproduced with Akai LPD8 mk1 (VID 09E8 PID 0075) on STM32H753 DWC2
host; fixed with this patch. See #3613 for full repro + captures.

change tuh_midi_rx/tx_cb() to have xferred_bytes
rename tuh_midi_get_num_rx/tx_cables() to tuh_midi_get_rx/tx_cable_count()
use default empty callback instead of weak null to be compatible with keil compiler

- add tuh_midi_packet_read_n() and tuh_midi_packet_write_n()
- add CFG_TUH_MIDI_STREAM_API to opt out stream API

- rename midi_stream_t to midi_driver_stream_t and move to midi.h (common for device and host)

- comment out tuh_descriptor_device_cb/tuh_desc_configuration_cb since it is unrelated to this PR
