get/set API (#244)
This pull request adds host-side HID API functions to get and set the HID protocol (boot vs. report mode), and introduces an optional device-sidecallback invoked when the protocol changes.
New features
- Added host-side APIs ux_host_class_hid_protocol_set() and ux_host_class_hid_protocol_get() with error-checking wrappers (_uxe_ variants).
- Added optional device-side callback ux_device_class_hid_set_protocol_callback, invoked when the host changes the active protocol.
- Added a comprehensive test to verify the new protocol callback functionality.
Bug fixes (host-side protocol get/set)
1. DMA buffer safety (protocol_get): The received byte is now written into a cache-safe allocated buffer instead of the caller's USHORT* directly. Stack memory is not DMA-safe on cache-incoherent embedded targets, and writing 1 byte into a USHORT* yields incorrect results on big-endianplatforms. Follows the same pattern as ux_host_class_hid_idle_get.
2. Missing device protection semaphore (both functions): In RTOS mode, ux_device_protection_semaphore is now acquired before submitting the transfer, in addition to the HID instance semaphore. All other HID control transfer functions (idle_get, idle_set) take both semaphores; omitting it allowed concurrent callers to corrupt the shared transfer_request fields.
3. Missing standalone locking (both functions): Added proper UX_HOST_STANDALONE support using UX_DISABLE/UX_RESTORE to atomically check and setUX_HOST_CLASS_HID_FLAG_LOCK and UX_DEVICE_FLAG_LOCK, and set UX_TRANSFER_FLAG_AUTO_DEVICE_UNLOCK + UX_TRANSFER_STATE_RESET on the transfer request before initiating. Follows the idle_get inline standalone pattern.

This commit cleans up header declarations by removing API and test prototypes that have no corresponding implementation in the repository.
Impact:
- No runtime behavior change.
- Compile/link surface is cleaner and more accurate for users and tests.

- Implements handling of UX_SLAVE_CLASS_CDC_ACM_SEND_BREAK in the CDC ACM control request path.
- Ensures break state is cleared on class deactivation to avoid carrying state across disconnect/reset cycles.
- Minor comment/whitespace cleanups in touched headers/sources.
- Testing: Build-only / compilation sanity/send break request. (no new automated tests added).

- Add mass-storage “removable media” support by tracking per-LUN prevent/allow medium removal and loaded/ejected status.
- Introduce an optional per-LUN callback to handle SCSI START STOP UNIT (including load/eject and power-condition fields).
- Extend storage constants (media types, sense keys/codes, power conditions, prevent flags) to support the new behavior and improve readability (explicit hex values).
- Initialize new per-LUN state on activation (default: medium removal allowed, medium loaded) and wire the new callback through storage initialization.
- Includes minor formatting/comment cleanups and version banner updates to 6.4.6.
