base: Split logging functions and PerfTimeLogger out of perftimer.h

base: Split logging functions and PerfTimeLogger out of perftimer.h

Soon PerfTimer will move into base/timer/ directory as it is already used by
production code.

This splits the logging stuff into their owns files and also moves
PerfTimeLogger into its own files.

BUG=None
TEST=base_unittests, ipc_perftests, etc...
