Add support for handling non-maskable interrupts (NMI) on TriCore
platforms. The NMI trap handler `tricore_nmitrap()` is provided as a weak
function that prints diagnostic information and invokes a panic with
register context. The main trap dispatcher will invoke `tricore_nmitrap`
when an NMI trap class is detected.
This change improves diagnostics when watchdog-induced NMIs or other
non-maskable exceptions occur during runtime.

Extend CONFIG_LIBCXXTOOLCHAIN support to all remaining platforms
in CMake builds by explicitly locating and linking libstdc++.a
from the toolchain. This prevents build failures caused by STL
header/library mismatches where toolchain headers are included
without the corresponding library.
* Adds nuttx_find_toolchain_lib() calls for all platforms.
* Aligns CMake behavior with Make build system.

Some Aurix Boot-FW configurations leave watchdogs enabled by default,
which can cause unexpected resets during early bring-up. This change
explicitly disables the CPU and system watchdogs during core0 startup to
ensure reliable system initialization.
- For TC3XX chips, call `IfxScuWdt_disableCpuWatchdog()` and
`IfxScuWdt_disableSafetyWatchdog()`.
- For TC4XX chips, call `IfxWtu_disableCpuWatchdog()` and
`IfxWtu_disableSystemWatchdog()`.
This is a low-risk startup change and does not alter watchdog behavior
after system initialization.

This patch adds support for building libsupc++ (the C++ runtime
support library from GCC's libstdc++-v3).
libsupc++ provides core C++ runtime support including:
- Exception handling (eh_*.cc)
- RTTI (Run-Time Type Information)
- Memory allocation operators (new/delete)
- Type info support
The implementation includes:
- libsupc++.defs for libsupc++ build integration
- support make and cmake build
- Use gthr.h, gthr-posix.h and unwind-pe.h from libgcc
- LIBSTDCXX_VERSION config option with default 14.2.0

When pressing Ctrl-C, the foreground process did not receive SIGINT
and failed to terminate.
The serial driver called nxsig_tgkill(-1, dev->pid, signo) from
interrupt context. With pid=-1, nxsig_dispatch() was called with
thread=true, which requires stcb->group == this_task()->group.
However, in interrupt context, this_task() returns the IDLE task,
whose group differs from the target process group. This caused
the signal dispatch to fail with -ESRCH.
Solution:
Replace nxsig_tgkill(-1, pid, signo) with nxsig_kill(pid, signo).
nxsig_kill() uses thread=false, which routes through group_signal()
without the same-group check, allowing signals to be delivered
correctly from interrupt context.
Impact:
- Fixes Ctrl-C signal delivery in serial console
- No API changes
- Affects serial driver interrupt handling only
Testing: Verified on QEMU ARM64 simulator with serial console

Release g_irqchainlock before calling irq_detach to avoid holding two locks
simultaneously, which can cause thread deadlock.
The irqchain_detach function was calling irq_detach while holding g_irqchainlock,
and irq_detach attempts to acquire g_irqlock. This lock ordering violation could
lead to deadlock in multithreaded scenarios.
Fix:
- Move spin_unlock_irqrestore(&g_irqchainlock, flags) before irq_detach call
- Ensure locks are released in proper order to prevent circular wait
This is part of the irq_chain_lock feature for safer IRQ chain handling.

The return address stored in the frame should point to the instruction
after the call. To get the actual call site, we need to subtract the
instruction size (sizeof(void *)) from the saved return address.
This ensures that backtrace addresses correctly point to the calling
instruction rather than the next instruction.
