Add SSE2, AVX2 & NEON support to pygame.print_debug_info()

[MyreMylar]

These are the most common instruction sets we support paths for and could assist us in detecting bugs. There are more instruction sets listed in system.get_cpu_instuction_sets() but currently we don't make much use of them in pygame-ce.

Great idea, will help detect bugs like the recent segfaults more easily

LGTM!

Thanks!

Ankith wanted to review this so slapping down a request changes to hold it until he can take a look.

I don't have a problem with this PR per se, but my opinion is that we should probably have a centralized way to get and set the SIMD level at runtime.

Everytime someone has to test a lower SIMD level they have to mess with either the buildconfig or the source code itself, and this is not ideal. Especially if we want a user to test out something.

One approach is to have env variables PG_ENABLE_[AVX2|SSE2|NEON] that can be configured before pygame init. On init, these variables are read, and along with runtime detection, we set the corresponding runtime check values.

Another approach is to have some API, probably in pygame.system, to pythonically get/set this

You should open an issue about that. It shouldn't block this PR.

We will get this for free when SDL3 comes out, btw. SDL_HINT_CPU_FEATURE_MASK.

True, I'm opening a separate issue for it, as it is independent of this PR.

Thanks for the PR 🎉

Starbuck approved, but requested changes so Ankith could review, Ankith approved, so I'm dismissing this so I can merge it
