[PATCH 1/4] pid: Replace pid bitmap implementation with IDR API

This patch replaces the current bitmap implemetation for Process ID allocation. Functions that are no longer required, for example, free_pidmap(), alloc_pidmap(), etc. are removed. The rest of the functions are modified to use the IDR API. The change was made to make the PID allocation less
