Added complete USBX Windows simulator regression support

[fdesbiens]

USBX had no Windows regression capability. The suite built and ran on Linux only, so defects specific to MSVC, to the LLP64 model and to the Windows simulator's tick behaviour could be found only by hand, if at all.

This adds Win64 and Win32 simulator ports for the regression suite, with architecture-selectable PowerShell entry points driving CMake, Ninja and the MSVC Build Tools, so nothing depends on the Visual Studio IDE. Windows timing is supplied through compile-time overrides rather than edits to shared test code: the simulator connect and disconnect sleeps, the enumeration debounce and a tick scale factor are macros whose Linux defaults reproduce the previous behaviour exactly, with the reduced values confined to the MSVC branch of the build. Genuine portability defects surfaced along the way and are fixed, including Win32 HID initialisation and pointer-width arithmetic.

Two consequences a reviewer would not predict from the diff. Twenty-seven regression sources came back from the Windows editor carrying a UTF-8 byte order mark, which has been stripped; those files are in the diff for their real changes, not for the mark. And the PowerShell helper now resolves its ThreadX, FileX and NetX Duo locations to sibling directories named after the upstream repositories, where it previously used names from one local checkout and failed for everyone else; -ThreadXDir, -FilexDir and -NetxduoDir override for a different layout.

Win64 430/430 and Win32 430/430, measured before the final comment, byte order mark and default path commits. On Linux, 433/433 default, 35/35 msrc_rtos and 45/45 standalone-host on the current head, with the AI disclosure check passing.

Depends on eclipse-threadx/threadx#736, eclipse-threadx/filex#100 and eclipse-threadx/netxduo#437, all merged.

threadx or threadx-fd ?
same for filex/netxduo

[fdesbiens]

Good catch, and it was a real defect rather than a naming question. The defaults now resolve to threadx, filex and netxduo. The suffixed names came from a local checkout and would not have resolved for anyone else, so the script failed out of the box. -ThreadXDir, -FilexDir and -NetxduoDir still override for a different layout.

This comment should be move under banner

[fdesbiens]

Done. The line sat between the banner's opening line and the first copyright line, splitting the banner open; it now follows the banner close.

Three other files in this branch had it in the same position and were corrected too: ux_host_class_dummy.c, usbx_class_multi_interface_enumeration_test.c and usbx_ux_host_class_hid_logitech_pro_x_superlight_test.c.
