Yabin Cui d4ac100948 perf/core: Save raw sample data conditionally based on sample type 
[ Upstream commit b9c44b9147 ]

Currently, space for raw sample data is always allocated within sample
records for both BPF output and tracepoint events. This leads to unused
space in sample records when raw sample data is not requested.

This patch enforces checking sample type of an event in
perf_sample_save_raw_data(). So raw sample data will only be saved if
explicitly requested, reducing overhead when it is not needed.

Fixes: 0a9081cf0a ("perf/core: Add perf_sample_save_raw_data() helper")
