Allow opt-in DCDs to queue transfers behind a halted endpoint without changing hardware DCD behavior.
Retry dummy_hcd's transient EP_SET_HALT failure, queue MSC BOT status and recovery requests behind the halt, and clean up Raw Gadget endpoint workers across bus reset.

Add a TinyUSB device controller driver for the Linux Raw Gadget
interface.
The driver implements the TinyUSB DCD API on top of the Linux
Raw Gadget userspace interface and supports:
- Control transfers (EP0)
- Bulk endpoints
- Interrupt endpoints
- Dynamic endpoint configuration
- Remote wakeup handling
- Stall and clear-stall
- Asynchronous transfer processing
Isochronous transfers are not supported because the Linux
Raw Gadget API does not expose the required functionality.
The implementation is intended for development, testing and
virtual USB devices running entirely in userspace on Linux.

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

The BSP family and MCU option were named "ch58x"/"CH58X", but the supported part is
the CH583/CH582 (and the SDK repo is openwch/ch583); CH585 is a separate MCU family,
so the CH58x umbrella was misleading. Rename to the specific family:
- hw/bsp/ch58x -> hw/bsp/ch583 (dir), and the BSP-local files ch58x_it.* ->
ch583_it.*, system_ch58x.* -> system_ch583.* (include guards/refs updated). The
vendor SDK files (CH58x_common.h, CH58x_*.c in hw/mcu/wch/ch583) keep their names.
- OPT_MCU_CH58X -> OPT_MCU_CH583 in tusb_option.h, tusb_mcu.h, and the shared WCH
USBFS driver (ch32_usbfs_reg.h, dcd_ch32_usbfs.c). OPT_MCU_CH582 is kept as an
alias (same value), so either name selects the same code.
- FAMILY_MCUS CH58X -> CH583, CFG_TUSB_MCU=OPT_MCU_CH583, mcu:CH58X -> mcu:CH583 in
the example skip lists, the CI build matrix (ci_set_matrix.py), the get_deps family
tag, and docs/reference/boards.rst.
Board names (ch582m_evt, yd-ch582m) are unchanged. Verified: make + cmake build for
ch582m_evt, and ci.lan HIL (all device examples pass).

Replace PR #3515's separate dcd_ch58x_usbfs.c / hcd_ch58x_usbfs.c with the
shared WCH USBFS device driver (combined per-endpoint control, like CH32V103),
adding two CH58x-specific behaviors guarded so CH32V103/V20x/V307 are unchanged:
- CH32_USBFS_EP_MANUAL_TOG: CH58x's hardware AUTO_TOG does not stay in sync, so
the ISR toggles DATA0/DATA1 manually and discards toggle-mismatched OUT
packets. Fixes multi-packet bulk-IN (e.g. MSC READ10) that otherwise hung.
- CH32_USBFS_EP4_SHARES_EP0: EP4 has no DMA register and overlays EP0's region
(EP0[0:63] + EP4 OUT[64:127] + EP4 IN[128:191]); add a 192-byte shared buffer
and buffer-pointer helpers (transparent for the other parts). Fixes
cdc_dual_ports (Port1 is on EP4).
Add the ch582m_evt board. Device only on USB0 (rhport 0): the shared
hcd_ch32_usbfs.c is CH32V20x-specific and cannot drive CH58x, so host / USB2
(rhport 1) is left commented out in the BSP for easy re-add.
Verified on ch582m_evt via local HIL: all device examples pass.

- Added a pending FIFO queue for asynchronous control transfers when the active slot is busy.
- Introduced `control_xfer_dispatch_pending` to handle queued transfers on slot availability.
- Improved synchronization for blocking and non-blocking transfer modes, preventing deadlocks in RTOS.
- Refactored and renamed related functions for clarity and consistency.
- Enhanced error handling and callback invocation for failed or stale transfers.

1. Add TU_LITTLE_ENDIAN_BITFIELD / TU_BIG_ENDIAN_BITFIELD macros in
tusb_compiler.h (GCC and IAR), following Linux kernel style.
2. Update bmAttributes (tusb_desc_endpoint_t) and bmRequestType_bit
(tusb_control_request_t) in tusb_types.h to use these macros with explicit
#error fallback if undefined.
3. Add tu_le16toh() conversion in dcd_event_setup_received() for
wValue/wIndex/wLength.
Tested on CIU98320B (big-endian ARM Cortex-M, full-speed HID keyboard).

- hcd_edpt_clear_stall: use ep_addr instead of hardcoded 0 (control endpoint)
- hcd: add TUP_USBIP_FSDEV_DRD define for MCUs with host support (C0, G0, H5,
U3, U5) and use it in hcd compile guard instead of enumerating MCUs
- dcd_edpt_close_all: use FSDEV_EP_COUNT instead of CFG_TUD_ENDPPOINT_MAX for
PMA btable offset to match handle_bus_reset
- midi host tuh_midi_stream_write: add missing cable_num to system messages,
SysEx, and real-time MIDI packets. Add 0xF mask for SysEx CIN checks.
Aligns with midi_device.c tud_midi_n_stream_write implementation.

In hwff_push_n() and hwff_pull_n(), the HWFIFO_ADDR_NEXT_N call after
processing the linear part of a wrap-around read/write used the data
byte count (lin_even) as the address stride increment. On STM32 FSDEV
PMA, data_stride=2 and addr_stride=4, so the pointer must advance by
(lin_even / data_stride) * addr_stride bytes, not lin_even bytes.
Fixes: 74e59e433 ("fix hwfifo pull/push n with address stride > 0")
