libuv: Allow windows UNC path with forward slashes
Fix libuv issue 3159 in CMake while integration in upstream libuv is pending.
No news of libuv maintainers to fix the issue directly in libuv repository (see https://github.com/libuv/libuv/pull/3167).
So I propose to fix it in CMake's copy of libuv.
Fixes: #22141 (closed)
Topic-rename: ctest-libuv-exe-network-path
