getdeps: fix xxhash build on windows

Summary:
fbthrift needs xxhash but xxhash manifest had no builder defined on windows

Add xxhash windows build support using cmake

Test Plan:

build xxhash locally on windows with:
python ./build/fbcode_builder/getdeps.py build xxhash

Before broken, no builder

Mapping scratch dir C:\Users\RUNNER~1\AppData\Local\Temp\fbcode_builder_getdeps-DZZaZfbthriftZfbthriftZbuildZfbcode_builder -> Z:\
Building on {distro=None, distro_vers=10, fb=off, fbsource=off, os=windows, shared_libs=off, test=off}

Exception: project xxhash has no builder for <getdeps.manifest.ManifestContext object at 0x0000021606FDE388>

After, works:

$ python ./build/fbcode_builder/getdeps.py build  xxhash
