Testing - Add support for ARM64 architecture (#1149)

- Allow the custom `tcl` vcpkg port to build on Windows ARM64 and map vcpkg architecture to Tcl’s NMAKE build flags.
- Add a `target-arch` input to the composite GitHub Actions used to configure/build OCCT, selecting the correct CMake `-A` architecture and vcpkg triplet.
- Adjust OCCT CMake vcpkg feature list macros to update `VCPKG_MANIFEST_FEATURES` in the current scope.
