Added Win64/VS 2022 port for FileX

[fdesbiens]

• New port: ports/win64/vs_2022/inc/fx_port.h
  • Based on the Win32 port; updated ALIGN_TYPE to ULONG64 for 64-bit pointers, added FX_REGRESSION_TEST hooks from the Linux port, and bumped the port name string to Win64/Visual.
• New CMake infrastructure: ports/win64/vs_2022/CMakeLists.txt
  • Exposes only the inc/ directory (port is header-only).
• Updated test/cmake/CMakeLists.txt
  • Added MSVC guards: skip -m32 / GCC coverage flags; locate VS 2022 toolchain; build ThreadX from source alongside FileX via THREADX_SOURCE_DIR.
• Updated test/cmake/regression/CMakeLists.txt
  • Added MSVC-compatible compile options (/W3 /Zi instead of -Wall -fprofile-arcs); added win64_compat include path for standalone + MSVC builds; added per-test TIMEOUT overrides for the two inherently long-running fault-tolerant tests on Windows.
• Updated test/cmake/samples/CMakeLists.txt
  • Added MSVC-compatible flag handling.
• New PowerShell scripts: scripts/build_fx.ps1, scripts/test_fx.ps1, scripts/fx_windows_common.ps1
  • Support all 9 build configurations; -Clean, -Config, -Verbose flags; modelled on the ThreadX Win64 build/test scripts.
• New Windows compatibility shims for standalone builds: test/regression_test/win64_compat/pthread.h test/regression_test/win64_compat/unistd.h
  • Minimal pthreads (CreateThread / WaitForSingleObject / TerminateThread) and usleep (Sleep) shims so standalone test files compile on MSVC.
• Fixed test/regression_test/fx_ram_driver_test.c and .h
  • RAM driver: added bounds check so out-of-range sector READs use a safe scratch buffer instead of segfaulting.
  • MSVC: large test buffers (ram_disk_memory_large, large_data_buffer, and standalone-mode ram_disk_memory / ram_disk_memory1) moved from BSS to calloc() via a .CRT\ constructor. This avoids the MSVC PE image 2 GB hard limit (LNK1248) and eliminates demand-zero page- fault overhead that would otherwise slow the test suite.
• Bulk-fixed 93 fault-tolerant test files
  • [FAULT_TOLERANT_SIZE] -> [FAULT_TOLERANT_SIZE > 0 ? FAULT_TOLERANT_SIZE : 1] so that MSVC C2466 (zero-length array) is not triggered when FX_ENABLE_FAULT_TOLERANT is not defined.
• Fixed filextestcontrol.c: standalone test runner thread exit
  • The Win64 pthread shim makes pthread_exit() a no-op so that test_control_thread_entry() proceeds to exit(failed_tests), giving ctest the correct process exit code.
• Fixed common/src/fx_utility_logical_sector_write.c
  • Added missing bounds guard to prevent sector-write past end of RAM disk during fault-tolerant interrupt simulation tests.

All 9 build configurations pass 136/136 regression tests on Win64/VS 2022.
