[PATCH v6 3/4] perf config: Prepare all default configs

[Taeung Song <treeze.taeung@gmail.com>]

To precisely manage configs,
prepare all default perf's configs that contain
default section name, variable name, value
and correct type, not string type.

In the near future, this will be used when
checking type of config variable or showing
all configs with default values, etc.
