Re-enable HAVE_NEON_INTRINSICS

[1bsyl]

It seems to me ARM_NEON is working and could be re-activated:

Does it build / work on windows versions too?

[1bsyl]

I haven't re-tried that, I think it did (window for window arm platform). never try compiling on windows for android.
I probably can double-check (later..)

What testing have you done to verify it?

[1bsyl]

I haven't done more testing recently. (I'll try the window compilation more later).
I don't know why this is back-out.
I've using these neon intrinsic routines for years now on android without special crash about it

[1bsyl]

I have some trouble to try the ARM compilation of SDL_ttf on window.
I have no device, my Visual Studio is old (2017) and not configured for ARM.
Would be nice if someone with a setup ready could try it.

Is this planned for 2.20 ?

Is this planned for 2.20 ?

No, nobody has a setup to test it, so it'll have to go in post-release.
