Rework posix_spawn locking and memory management:
 - always provide a vmspace for the new proc, initially borrowing from proc0
   (this part fixes PR 46286)
 - increase parallelism between parent and child if arguments allow this,
   avoiding a potential deadlock on exec_lock
 - add a new flag for userland to request old (lockstepped) behaviour for
   better error reporting
 - adapt test cases to the previous two and add a new variant to test the
   diagnostics flag
 - fix a few memory (and lock) leaks
 - provide netbsd32 compat
Fix asynchronous posix_spawn child exit status (and test for it).
