wangjianyu3 4775b36316 drivers/usbdev: add UVC gadget class driver 
Add USB Video Class 1.1 gadget driver supporting Bulk transport
with uncompressed YUY2 video streaming. Resolution and frame
interval are negotiated dynamically via PROBE/COMMIT control.

- uvc.h: protocol constants, streaming control struct, public API
- uvc.c: class driver with PROBE/COMMIT, bulk EP, /dev/uvc0 chardev
- Kconfig/Make.defs: USBUVC config and build rules
- boardctl.c: BOARDIOC_USBDEV_UVC standalone init path

Hardened against host disconnect:
- Removed nxmutex_lock from USB interrupt context paths
- Added 30s semaphore timeout in uvc_write with EP_CANCEL fallback
- Drain stale wrsem counts in VS_COMMIT before new stream
- Guard uvc_streaming_stop() against double EP_CANCEL race
- Handle EP_SUBMIT returning -ESHUTDOWN gracefully
