Added Win64/VS 2022 port for FileX (#94)

- 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.
