Disable Tuple#to_static_array spec on AArch64

[HertzDevil]

Fixes #14835

Should we disable the Implementation as well?

[HertzDevil]

It is still used in #12960 right? It is probably easier to disallow anything below LLVM 13 when targetting AArch64

[straight-shoota]

Yes. But other parts of the standard library still work with LLVM < 13 on aarch64. So I'd suggest to use the same macro condition to raise a compile time error in Tuple#to_static_array.
But we can do that independently. This could be good to go on its own.

The problem lies not within this method (plus StaticArray#sort_by) but within LLVM itself, I could trigger a crash by simply doing p StaticArray[1, 'a'] so a few methods aren't going to cut it.

Unfortunately we cannot remove support for LLVM 12 and below on all platforms right away, because Crystal 1.0.0 only supported up to 11.
