Revert use of libuv for process execution for 3.28

Browse Source 
Wide use of CMake 3.28.{1,0[-rcN]} has uncovered some hangs and crashes
in libuv SIGCHLD handling on some platforms, particularly in virtualization
environments on macOS hosts.  Although the bug does not seem to be in CMake,
we can restore stability in the CMake 3.28 release series for users of such
platforms by reverting our new uses of libuv for process execution.

Revert implementation changes merged by commit 4771544386 (Merge topic
'replace-cmsysprocess-with-cmuvprocesschain', 2023-09-06, v3.28.0-rc1~138),
but keep test suite updates.
