perf/x86/intel/ds: Handle PEBS overflow for fixed counters

The pebs_drain() need to support fixed counters. The DS Save Area now
include "counter reset value" fields for each fixed counters.

Extend the related variables (e.g. mask, counters, error) to support
fixed counters. There is no extended PEBS in PEBS v2 and earlier PEBS
format. Only need to change the code for PEBS v3 and later PEBS format.

Extend the pebs_event_reset[] logic to support new "counter reset value" fields.

Increase the reserve space for fixed counters.
