perf arm_spe: Allow parsing both data source and events
Current code skips to parse events after generating data source. The
reason is the data source packets have cache and snooping related info,
the afterwards event packets might contain duplicate info.
This commit changes to continue parsing the events after data source
analysis. If data source does not give out memory level and snooping
types, then the event info is used to synthesize the related fields.
As a result, both the peer snoop option ('-d peer') and hitm options
('-d tot/lcl/rmt') are supported by Arm SPE in 'perf c2c'.
