fix(sample): Drop cpuid_metric event from sample writing.

Since 8f3ac68, we do not support systems that do not have perf_attr.context_switch anymore. This means that since then, samples will always be enclosed in context switch events, removing the need for writing the cpuid metric from samples. Also remove src/perf/syscall/sample/writer.cpp. Apparently this is completely dead code
