libuv: win/spawn: disable extra-file-descriptor support not needed by CMake
Upstream libuv supports passing file descriptors >= 3 to child processes
via `STARTUPINFOW` members reserved by the MSVC C run-time. However,
some programs use `GetStartupInfoW` to initialize a `STARTUPINFOW`
structure to pass to `CreateProcessW` without clearing the reserved
members. If we launch such programs with non-zero values in the
reserved members, the MSVC C run-time in *their* children may not
correctly associate the stdin/stdout/stderr streams' file descriptors
with the corresponding `HANDLE`s.
Patch our copy of libuv to avoid using the reserved members. This
restores `execute_process` support for the above-described programs as
we had prior to commit 5420639a8d (cmExecuteProcessCommand: Replace
cmsysProcess with cmUVProcessChain, 2023-06-01, v3.28.0-rc1~138^2~8).
It also enables support for such programs when launched by `ctest`.
