sched/spawn: remove spawn proxy thread to simplify task/posix_spawn()

Browse Source 
The spawn proxy thread is a special existence in NuttX, usually some developers
spend a lot of time on stack overflow of spawn proxy thread:

https://github.com/apache/nuttx/issues/9046
https://github.com/apache/nuttx/pull/9081

In order to avoid similar issues, this PR will remove spawn proxy thread to simplify
the process of task/posix_spawn().

1. Postpone the related processing of spawn file actions until after task_init()
2. Delete the temporary thread of spawn proxy and related global variables
