Removes a bunch of epee garbage and replaces it with std::chrono.
In particular:
- TIME_MEASURE_* macros are gone because they are garbage.
- epee::get_tick_count() is gone because it is garbage.
- epee::get_ns_count() is gone because it is garbage.
- TIME_MEASURE_NS_* macros are gone because they are unused and garbage.
- PROFILE_FUNC_* macros are gone because they are unused and garbage.
- profile_tools::local_call_account is gone because it is unused and
garbage.
- various places passing around ints (which could be seconds,
milliseconds, or nanoseconds) changed to pass std::chrono duration
types.
