darwin,libuv: use posix_spawn

Spawning child processes in an Electron application with a hardened runtime has become slow in macOS Big Sur. This patch is a squashed version of libuv/libuv#3064, with the addition of API availability annotations to fix a build warning (since Electron compiles with the `-Wunguarded-availability-new` flag). This patch should be removed when libuv PR 3064 is merged.
