perf stat: Revert "perf stat: Add default hybrid events"

This reverts commit Fixes: ac2dc29edd21f9ec ("perf stat: Add default
hybrid events")

Between this patch and the reverted patch, the commit 6c1912898ed21bef
("perf parse-events: Rename parse_events_error functions") and the
commit 07eafd4e053a41d7 ("perf parse-event: Add init and exit to
parse_event_error") clean up the parse_events_error_*() codes. The
related change is also reverted.

The reverted patch is hard to be extended to support new default events,
e.g., Topdown events, and the existing "--detailed" option on a hybrid
platform.

A new solution will be proposed in the following patch to enable the
perf stat default on a hybrid platform.
