merge revision(s) 35249,35250: [Backport #6296]

* include/ruby/win32.h (rb_w32_aspawn_flags): add the declaration of
  new function.

* process.c (enum): add EXEC_OPTION_PGROUP and move the position
  above for the usage in proc_spawn_n().

* process.c (proc_spawn_n): add an argument to pass new option
  `new_pgroup`. The option specifies CREATE_NEW_PROCESS_GROUP flag to
  CreateProcessW(). This flag is necessary for the usage of
  Process.kill on the subprocess on Windows.

* process.c (rb_exec_arg_addopt): ditto.

* process.c (rb_spawn_process): ditto.

* process.c (documentation for rb_f_spawn): add documentation for new
  option `new_pgroup` of spawn.

* test/ruby/test_process.rb (TestProcess#test_execopts_new_pgroup):
  add tests for option `new_pgroup`.

* test/ruby/test_thread.rb
  (TestThreadGroup#test_thread_timer_and_interrupt):
  add option `new_pgroup: true` to spawn on Windows. It's needed for
  Process.kill on a subprocess.

* win32/win32.c (CreateChild): add an argument to pass
  dwCreationFlags of CreateProcessW().

* win32/win32.c (rb_w32_spawn): ditto.

* win32/win32.c (rb_w32_aspawn_flags): add new function to pass
  dwCreationFlags.

* win32/win32.c (rb_w32_aspawn): refactor to move the content to
  rb_w32_aspawn_flags().
  [ruby-core:43245][Bug #6131]

* test/ruby/test_thread.rb
  (TestThreadGroup#test_thread_timer_and_interrupt): skip on Windows.
  Process.kill cannot kill a subprocess if CREATE_NEW_PROCESS_GROUP
  flag is not specified in a call to CreateProcessW().

* win32/win32.c (CreateChild): revert the usage of
  CREATE_NEW_PROCESS_GROUP flag for compatibility.
