[PATCH v1 3/9] perf auxtrace: Refactor auxtrace__evsel_is_auxtrace()

[Leo Yan <leo.yan@arm.com>]

The auxtrace__evsel_is_auxtrace() function invokes the callback
.evsel_is_auxtrace() to check if an event is an AUX trace. In the
low-level code, every AUX trace module provides its callback to
compare the PMU type.

This commit refactors auxtrace__evsel_is_auxtrace() by simply
calling evsel__is_aux_event() rather than using the callback function.
As a result, the callback .evsel_is_auxtrace() is no longer needed, so
the definition and implementations are removed.
