addresses to devices, and this patch can add support for this.

If the wdog use the fine-grained spin-lock, and allow the callback execution without the lock held, there will be incorrect interleaving.
E.g. The first `nxsem_timeout` callback function caused the second semaphore wait to fail.
Core 0 [nxsem_clockwait] | Core 1
enter_critical_section() | ...
wd_start(nxsem_timeout) | ...
nxsem_wait(sem) | wd_expiration() --> nxsem_timeout
wd_cancel(&rtcb->waitdog) | try enter_critical_section()
leave_critical_section() | Failed retry...
....nxsem_clockwait | Failed retry...
enter_critical_section() | Failed retry...
wd_start(nxsem_timeout) | Failed retry...
nxsem_wait(sem) | Core 1 enter the critical section
| nxsem_wait_irq(wtcb, ETIMEDOUT) -> incorrectly wake-up the rtcb.

Add new RISC-V 64-bit QEMU configuration with:
- 64-bit RISC-V (RV64) architecture support
- RISC-V Vector Extension (RVV/V-extension) enabled
- LVGL graphics framework integration
- VirtIO GPU and input device support
- NSH shell with built-in applications
This configuration enables developers to build and test LVGL graphical
applications on 64-bit RISC-V targets with Vector extension support,
providing a foundation for future SIMD optimization work.
Includes:
- defconfig: Complete configuration file with all necessary options
- Updated index.rst: Build and run instructions with QEMU launch command

The value returned by sizeof(struct note_start_s) is larger
than the actual memory footprint of struct note_start_s.
This causes the length calculated in sched_note_start to be larger
than the actual memory size,which further leads to out-of-bounds reads in note_common.

According to the definitions of PF_PACKET and SOCK_DGRAM,
extend the current protocol stack pkt protocol to support SOCK_DGRAM mode.
Some third-party network libraries use AF_PACKET, SOCK_DGRAM type sockets
to construct packets and send/receive data, This patch can add support
