Gate libuv path to Windows and add fallback for unsupported platforms

Browse Source 
- Change #else to #elif OS(WINDOWS) to explicitly guard libuv code
- Add final #else with ENOTSUP error for platforms without support
- This matches the pattern used in Process_functionCpuUsage
- Prevents compilation failures on non-Linux/non-Darwin/non-Windows targets (e.g., BSD)

Note: Bundled libuv is v1.51.0 which includes uv_getrusage_thread (added in v1.50.0)
