libperf: Add perf_thread_map__new_dummy() function

Moving the following functions:

  thread_map__new_dummy()
  thread_map__realloc()
  thread_map__set_pid()

to libperf with the following names:

  perf_thread_map__new_dummy()
  perf_thread_map__realloc()
  perf_thread_map__set_pid()

the other 2 functions are dependencies of the
perf_thread_map__new_dummy() function.

The perf_thread_map__realloc() function is not exported.
