perf session: Add ability to 'skip' a non-piped event stream
A piped event stream may contain arbitary sized tracepoint information
following a PERF_RECORD_HEADER_TRACING_DATA event. The position in the
stream has to be 'skipped' to match the start of the next event.
Provide the same ability to a non-piped event stream to allow for
Instruction Trace data that may also be in a non-piped event stream.
