perf parse-events: Remove unused macros __PERF_EVENT_FIELD()

Unused macros reported by [-Wunused-macros].

This macros were introduced as __PERF_COUNTER_FIELD and used for reading
the bit in config.

cdd6c482 ("perf: Do the big rename: Performance Counters ->
Performance Events") Changes it to __PERF_EVENT_FIELD but at this commit
there is already nowhere else using these macros, also no macros called
PERF_EVENT_##name##_MASK/SHIFT.

Now we are not reading type or id from config. These macros are useless
and incomplete.

So removing them for code cleaning.
