Subject: [PATCH v9 2/7] perf config: Add macros assigning key-value pairs to default_config_item

In near future, default_config_item arrays will be added
(e.g. const struct default_config_item colors_config_items[])
To simply assign config key-value pairs to default_config_item,
add macros that are CONF_VAR() and CONF_*_VAR() for each type.
