Fix detection of CMake-built libuv on Windows

As of libuv 1.36.0, CMake is the only supported build method for libuv
on Windows.  Account for that fact by adjusting the relevant paths and
DLL file names used in the win32utils/Configure script.  Update
Windows-specific documentation accordingly.

(cherry picked from commit 64a091d587058641e0b7528054efd92cbb635f41)
