[SPE] Add `--dump-raw-trace` support in `wperf record`

[PrzemekWirkus]

Description

We can add new command line option for wperf sample / record with SPE is used, --dump-raw-trace.
We already have SPE raw buffer parser which can detect packets and records. We also store spe.data buffer which contains this buffer.

Example raw SPE fill buffer text output could be:

Output will contain raw SPE data and its textual representation, such as:

0xc7d0 [0x30]: PERF_RECORD_AUXTRACE size: 0x82f70  offset: 0  ref: 0x1e947e88189  idx: 0  tid: -1  cpu: 2

Note: this function can be used in the future also in wperf report - a new feature we can add in the future.

See example from perf tools: Add ARM Statistical Profiling Extensions (SPE) support.

Definition of done

• Add new command line option --dump-raw-trace.
• Add parser output to SPE JSON (sampling) output.
• [TBD] Add raw spe.buffer to SPE JSON (sampling) output.
• Verify output from this implementation with spe-parser provided with Telemetry Solution. You can find spe-parser in TS Gitlab repo.
  • Note: spe-parser should have new option -r/--raw-buffer that will treat input file
    as a raw SPE fill buffer content. It will allow you to output for the same spe.data file SPE packets.
