[PATCH v2 0/3] perf arm-spe: Add snapshot mode support

This patchset adds snapshot mode support for arm-spe.

  - [PATCH 1/3] implements the minimal callbacks to support recording in
    snapshot mode.
  - [PATCH 2/3] implements the find_snapshot callback in order to handle
    wrap-arounds in the AUX buffer.
  - [PATCH 3/3] adds a test for spe snapshot mode.

Changes since v1:
  - Added acme@kernel.org to the recipients list as I forgot to include
    him in the original patchset [1].
  - Removed [PATCH 1/5] and [PATCH 2/5] in order to keep patches
    semantically relevant.
  - Updated test script test_arm_spe.sh because it wasn't working on
    distributions that use dash shell v0.5.10 (ubuntu 20) [2].
