[PATCH v8 2/5] perf config: Bring declarations about config from util/cache.h to util/config.h

[Taeung Song]

Lately util/config.h has been added
but util/cache.h has declarations of functions
and extern variable for config features.

To manage codes about configuration at one spot, move them
to util/config.h and util/cache.h include util/config.h
