perf config: Add stat.big-num support
Add support for new "stat.big-num" boolean option.
This allows a user to set a default for "--no-big-num" for "perf stat"
commands.
--
$ perf config stat.big-num
$ perf stat --event cycles /bin/true
Performance counter stats for '/bin/true':
778,849 cycles
[...]
$ perf config stat.big-num=false
$ perf config stat.big-num
stat.big-num=false
$ perf stat --event cycles /bin/true
Performance counter stats for '/bin/true':
769622 cycles
[...]

There is an interaction with "--field-separator" that must be
accommodated, such that specifying "--big-num --field-separator={x}"
still reports an invalid combination of options.
Documentation for perf-config and perf-stat updated.
