This is a WIP.

Enabled only when the build with DEBUG=1.

BPFPerfEventWrites counts the number of events processed by the eBPF
programs and written to the perf event buffer.

It is incremented right before the event is written to the perf buffer,
making it possible to measure even if the event is lost.

This metric can be used to monitor the performance of individual eBPF
events and to detect potential bottlenecks.
