This commit updates the __stack_size definition in the
linker flags, changing its value from 350 to 352. This
change ensures that the stack size is a multiple of 16,
aligning the stack pointer (sp) to a 16-byte boundary
as required by the system architecture.

Compiling this demo with picolibc 1.8.9 (as packaged with Debian trixie)
results in a stack overflow. Increasing the minimal stack size from
80 to 88 bytes resolves this. (Debian trixie arm crosscompiler defaults
to compile/link against picolibc and not newlib anymore.)

SoftConsole failed to execute MI command to load the RTOSDebug.elf built in this project. Since the debugger couldn't find address `0xe000ed00` defined in ARM processor.
We need to set `$target_riscv` to 1 so that the gdb can be initialized correctly.
On Ubuntu 24.04 ARM64, PTHREAD_STACK_MIN is 0x20000 which does not fit
in unsigned short, size of which is 2 bytes. Casting PTHREAD_STACK_MIN
to unsigned short in FreeRTOSConfig.h results in
configMINIMAL_STACK_SIZE getting defined to 0 which leads to SIGSEV.
This change removes the not needed casting of PTHREAD_STACK_MIN to
unsigned short.

* Exclude unnecessary directories from build.

4. "FreeRTOS+Trace Recorder/kernelports/ESP-IDF_FreeRTOS"
5. "FreeRTOS+Trace Recorder/kernelports/ThreadX"
6. "FreeRTOS+Trace Recorder/kernelports/Zephyr"
1 is applied to both of "Debug" configuration and "Debug_CodeCoverage" configuration.
Others are applied to only "Debug" configuration because those directories are already excluded from build on "Debug_Coverage" configuration.
* Include path setting is modified.
1.Directory name is modified.("Include" -> "include")
2.New path is added.(FreeRTOS+Trace Recorder/kernelports/FreeRTOS/include)
These modifications are needed to build "Debug" configuration. They are not needed for "Debug_CodeCoverage" configuration because these paths are not used. But these modifications are applied to both of "Debug" configuration and "Debug_CodeCoverage" configuration because of future potential risk.
* [WIN32-MingW Demo] Replace "Exclude from Build" by "Resource Filter".
"Resource Filter" is better than "Exclude from Build" because "Resource Filter" makes excluded directories invisible on Eclipse GUI. But some directories are still "Exclude from Build" because they should be excluded only on "Debug_CodeCoverage" configuration. "Resource Filter" cannot be specified to each configuration separately.

* [WIN32-MSVC Demo] Add tick type width definition based on the target platform.(32bit/64bit)
32bit TickType_t is used on Win32 target. 64bit TickType_t is used on x64 target.
Reason of change: Before this change, 32bit TickType_t is always used in MSVC demo. It is inefficient for 64bit target. In addition, compiler reported warnings for the cast operation between TickType_t and (void *) pointer if the target is x64 because of different width. 64bit TickType_t should be used instead of 32bit if target is 64bit.
* [WIN32-MSVC Demo] Change type of some variables from uint32_t to UBaseType_t.
Reason of change: These variables are cast to/from pointer type in existing codes. x64 compiler reports warnings for the cast operations between uint32_t and pointer type. UBaseType_t solves those warnings because it has same width as pointer type on both of Win32 platform and x64 platform.
* [WIN32-MSVC Demo]Correct prefix of variables and indent to follow coding style guide.
* [WIN32-MSVC Demo]Correct type of the argument in vApplicationGetIdleTaskMemory() prototype declaration.
It is corrected to match original declaration described in task.h.
* [WIN32-MSVC] Add cast operation to solve compiler warnings on x64 platform.
Before this change, compiler claimed that the cast operation to wider type should be applied before other arithmetic operations because of overflow risk. There is no overflow risk here but it is modified to solve compiler warnings.
* [WIN32-MingW Demo] Add tick type width definition based on compiler type.(32bit/64bit)
32bit TickType_t is used if compiler is MinGW32. 64bit TickType_t is used if compiler is MinGW64.
Reason of change: Before this change, 32bit TickType_t is always used in MinGW demo. It is inefficient for 64bit compiler. In addition, MinGW64 reported warnings for the cast operation between TickType_t and (void *) pointer because of different width. 64bit TickType_t should be used instead of 32bit if compiler is 64bit.
* [WIN32-MingW Demo] Change printf() format specifiers from %u to %llu.
Reason of change: %u specifier corrupts 64bit tick count because it supports only 32bit value. %llu can be used for both of 64bit value and 32bit value.(After casting to 64bit)
* [WIN32-MingW Demo] Change type of some variables from uint32_t to UBaseType_t.
Reason of change: These variables are cast to/from pointer type in existing codes. 64bit compiler(MinGW64) reports warnings for the cast operations between uint32_t and pointer type. UBaseType_t solves those warnings because it has same width as pointer type on both of MinGW32 and MinGW64.
* [WIN32-MingW Demo] Change type of some variables from uint32_t to UBaseType_t.
Same change as previous commit is applied to source codes which are built only on Debug configuration.
* [WIN32-MingW Demo] Add brackets to the condition in #if statement. Behavior is not changed. Reason of change is to follow coding style guide of FreeRTOS.
* Update "FreeRTOS/Source" submodule(FreeRTOS-kernel) to #1008.
