[PATCH 00/25] perf arm_spe: Extend operations

[Leo Yan]

This series enhances tooling to support new operations:

  - Support for MTE tag since Arm SPE v1.3;
  - Support for Advanced SIMD extension and SVE operations;
  - Support memcpy, memset and GCS operations;
  - Support extended operations for atomic, Acquire/Release and
    Exclusive instructions.
  - Enhance the data source for associated info, like floating-point,
    conditional, data processing, etc.

This series is divided into three parts:

  Patches 01 ~ 06: Support raw dump for new operations;
  Patches 07 ~ 18: Export the operation info into records, so that the
                   information can be later consumed by samples.
  Patches 19 ~ 25: Set the operation info into sample's data source and
                   SIMD flag, and updated the document.

This patch series is tested on FVP. I verified Arm SPE trace data with
kselftest's MTE tag test and SVE test. For GCS test, I verified the SPE
decoding with I manually modifying perf binary file.
