test: v8: Add test-linux-perf-logger test suite

[lukealbao]

This patch adds test coverage for the --perf-prof-basic* v8 flags.

This ports the repro from #50225, which is fixed in main as of f6f681b.

Relatedly, but out of scope here: I believe this also enables removal of the flaky perf(1) integration tests reported in #50079. Those tests missed the bug reported in #50225. They also don't strictly need to integrate with perf, as far as I can tell. The integration point (the perf map file) is done out-of-band from the perf recording; it is enabled via the v8 flags. See dso__load_perf_map for details on how it is consumed.

@lukealbao so that I understand correctly. This improves on v8-updates/test-linux-perf because it validates the output which is fed into perf instead of needed to run perf itself which is where we had the mismatch problem in #50079?

[lukealbao]

👋 @mhdawson that's exactly right.

I had considered simply to extend v8-updates/test-linux-perf with the new repro cases, but I realized that the coverage doesn't offer anything that's not available from the perf map file. I'm hoping to land this test suite in any case, so I didn't want to presume to remove the integration test without further input.

@lukealbao thanks for confirming that makes sense to me.

Test failures are #50373. Being fixed by #50375. Will need a fresh (not resumed) CI run to pick up the change when it lands on main.
