boot mode is configured
1. Explicitly define the .rtc_reserved section to ensure RTC data
that requires fixed address is correctly placed and does not
conflict with other sections
2. When legacy boot is configured, vecbase must also be set and
clear the BSS section
3. Cache must be disabled during Flash operations, so all
Flash-operation-related functions must be placed in IRAM
(internal RAM). Update the linker script for legacy boot mode

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.

Add validation to ensure allocated stack size does not exceed TLS_MAXSTACK when
CONFIG_TLS_ALIGNED is enabled, and verify proper stack alignment using STACK_ALIGN_MASK
across all architectures. This improves stack safety and prevents potential TLS overflow conditions.

Rename STACK_ALIGNMENT macro to STACKFRAME_ALIGN throughout the codebase
to provide clearer naming semantics. The new name better reflects the macro's

Move stack alignment and kernel stack macros from architecture-specific internal

After addrenv_switch(), the current running task (this_task) may change due to
deferred work execution. Update all architecture interrupt, syscall, and exit
handlers to re-fetch tcb = this_task() after addrenv_switch(). Ensures scheduler
and context operations use the correct TCB, preventing context corruption and
exceptions across SMP and memory-protected builds.

Directly downloading the Git repository is inconvenient for local debugging.
This will allow to automatically download external packages from the Internet.
If not set, the repo need to be download will need to provide them manually,
otherwise an error will occur and the build will be aborted.
Add `USE_NXTMPDIR_ESP_REPO_DIRECTLY`, with this we can use
`USE_NXTMPDIR_ESP_REPO_DIRECTLY=y make` which can directly use esp-hal-3rdparty
under nxtmpdir without CLONE, CHECK_COMMITSHA, reset, checkout and update. Just
`cp -rf nxtmpdir/esp-hal-3rdparty chip/$(ESP_HAL_3RDPARTY_REPO)`.

Nuttx currently has 2 types of sleep interfaces:
1. Signal-scheduled sleep: nxsig_sleep() / nxsig_usleep() / nxsig_nanosleep()
Weaknesses:
a. Signal-dependent: The signal-scheduled sleep method is bound to the signal framework, while some driver sleep operations do not depend on signals.
b. Timespec conversion: Signal-scheduled sleep involves timespec conversion, which has a significant impact on performance.
2. Busy sleep: up_mdelay() / up_udelay()
Weaknesses:
a. Does not actively trigger scheduling, occupy the CPU loading.
3. New interfaces: Scheduled sleep: nxsched_sleep() / nxsched_usleep() / nxsched_msleep() / nxsched_ticksleep()
Strengths:
a. Does not depend on the signal framework.
b. Tick-based, without additional computational overhead.
Currently, the Nuttx driver framework extensively uses nxsig_* interfaces. However, the driver does not need to rely on signals or timespec conversion.
Therefore, a new set of APIs is added to reduce dependencies on other modules.
(This PR also aims to make signals optional, further reducing the code size of Nuttx.)
