perf stat: Move 'initial_delay' to 'struct perf_stat_config'

Browse Source 
Move the static 'initial_delay' variable to 'struct perf_stat_config',
so it can be passed around and used outside the 'perf stat' command.

Add 'struct perf_stat_config' argument to create_perf_stat_counter() and
use its 'initial_delay' member instead of the static one.
