First commit for VPR5_Parallel

Due to some functions in VPR5_Parallel had a lot of parameters. I hated
it badly. Now I new add 2 ADTs in place_parallel.h: thread_local_common_paras_t
and thread_local_data_for_swap_t to simplyfied it.
update and simplify parameters in vpr5_paraplace
Simplified try_swap_parallel
