perf report: Set PERF_SAMPLE_DATA_SRC bit for Arm SPE event

Since commit bb30acae4c4dacfa ("perf report: Bail out --mem-mode if mem
info is not available") "perf mem report" and "perf report --mem-mode"
don't report result if the PERF_SAMPLE_DATA_SRC bit is missed in sample
type.

The commit ffab487052054162 ("perf: arm-spe: Fix perf report
--mem-mode") partially fixes the issue.  It adds PERF_SAMPLE_DATA_SRC
bit for Arm SPE event, this allows the perf data file generated by
kernel v5.18-rc1 or later version can be reported properly.

On the other hand, perf tool still fails to be backward compatibility
for a data file recorded by an older version's perf which contains Arm
SPE trace data.  This patch is a workaround in reporting phase, when
detects ARM SPE PMU event and without PERF_SAMPLE_DATA_SRC bit, it will
force to set the bit in the sample type and give a warning info.
